Senate Confirmation Powers: How One Senator Can Block Fed Nominees

Last updated 3 months ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

One senator has frozen the Federal Reserve’s leadership. The North Carolina Republican was talking about Federal Reserve nominations, and he meant every word. The Justice Department must drop its criminal investigation of Fed Chair Jerome Powell before he will vote to confirm anyone—not Kevin Hassett, not Kevin Warsh, not a Nobel Prize-winning economist, not his own mother—to lead the central bank.

One lawmaker can potentially freeze the leadership of the institution that sets interest rates for the entire American economy.

This is how the confirmation process works when a member decides to use the full weight of powers that most Americans don’t know exist. Right now, that obscure constitutional machinery has collided with something new: a sitting president using federal prosecutors to threaten the Federal Reserve chair with criminal charges, apparently because Powell won’t lower interest rates on command.

The nominal reason for the investigation? Powell’s congressional testimony about cost overruns on the Fed’s headquarters renovation. The building project ballooned from $1.9 billion to $2.5 billion, and prosecutors claim Powell may have misled Congress about the reasons. But the timing tells a different story. Trump has spent months publicly demanding Powell’s resignation and calling for rate cuts. When Powell refused to bend, a criminal investigation was opened by U.S. Attorney Jeanine Pirro following a referral from Rep. Anna Paulina Luna.

The North Carolina Republican announced his blockade. The arcane rules governing Senate confirmations became the only thing standing between presidential pressure and the independence of America’s central bank.

How Individual Senators Can Block Federal Reserve Nominees

The Constitution says the Senate must confirm presidential appointments, but it doesn’t specify how. That “how” has evolved into a system where individual members wield extraordinary leverage through mechanisms that sound bureaucratic but function like veto powers.

Start with the blue slip—a formal notification where home-state senators indicate support for a nominee.

Any member can block a vote on a nomination, preventing it from being voted on by the full Senate. These blocks can be anonymous or public, temporary or indefinite. The North Carolina Republican made his block public.

The Senate Banking Committee, which oversees Fed nominations, has thirteen Republicans and eleven Democrats. The North Carolina lawmaker sits on that committee. If he refuses to vote a nominee out of committee, the committee chair can’t force a vote without his cooperation. You need a majority to advance nominees, and if one Republican consistently votes no, that majority evaporates.

Even if a nominee cleared committee over his objection, Senate floor procedures offer more chokepoints. Any member can object to agreements to speed up routine votes, forcing the majority leader to pursue a special vote to end debate (called cloture) requiring 60 votes. With the Senate split 52-48, Republicans need Democratic support to hit that threshold. Democrats have their own reasons to block Trump’s Fed nominees right now.

The North Carolina Republican doesn’t need to hold the line alone—he has a bipartisan coalition, even if Democrats lack the votes to block nominees by themselves.

Senate Majority Leader John Thune faces an impossible choice. He can try to ram through a nominee over the objection, which means a public Republican civil war during Trump’s presidency. He can change Senate rules to eliminate the 60-vote threshold for Fed nominees, destroying one of the last remaining checks on executive power. Or he can wait for the standoff to resolve itself somehow.

Thune’s public comments suggest he’s chosen the third option: someone needs to back down, and it won’t be him forcing the issue.

What Powell Testified About and Why the Charges Are Weak

In June 2025, Powell testified before the Senate Banking Committee about the Fed’s headquarters renovation. The project had grown expensive—$2.5 billion, up from an initial $1.9 billion estimate. Powell explained that asbestos and lead contamination discovered during construction had driven up costs, along with inflation in construction materials and additional safety upgrades the Fed deemed necessary once work began.

He provided extensive documentation. A follow-up letter to Banking Committee Chair Tim Scott detailed the history of the buildings, the nature of repairs required, and the budgetary approvals at each stage. The core work involved updating electrical, plumbing, and HVAC systems that were beyond their useful lives.

Nothing about this testimony appears to have personally benefited Powell. He didn’t profit from the renovation. He didn’t gain job security by lying about building costs. The Fed had been transparent about cost overruns in public filings.

Federal perjury laws require proof that someone knowingly lied under oath. Obstruction of justice requires proof of blocking or interfering with a federal investigation. Legal experts have struggled to articulate what crime Powell allegedly committed.

But prosecutorial power inflicts damage regardless of case strength. Indictment carries professional, financial, and reputational consequences even if the accused is ultimately acquitted. Powell would face years of litigation, millions in legal fees likely paid out of his own pocket, and constant background noise about alleged conduct. The process becomes the punishment.

Why Federal Reserve Independence Matters

The Federal Reserve was created in 1913 specifically to manage monetary policy independent of short-term political pressure. That independence exists because history provides clear evidence of what happens when central banks become controlled by political leaders.

The pattern repeats across countries and decades: political leaders pressure the central bank to lower interest rates before elections. The central bank complies to maintain its relationship with political leadership. Short-term growth accelerates. Prices begin rising. By the time the damage becomes apparent, inflation has become entrenched and difficult to suppress.

Investors lose confidence that their money will hold value. The currency weakens. Interest rates rise not because of central bank policy but because bond investors demand higher yields to compensate for inflation risk.

The Federal Reserve Act legally protects this independence by giving Board members fourteen-year terms staggered so no president can replace them all at once. They can only be fired for serious misconduct, not for making unpopular decisions. The Fed’s job is to focus on keeping prices stable and creating jobs, not on supporting the president’s economic agenda.

But legal protections only work if people enforce them. Right now, enforcement depends on whether members like the North Carolina Republican view Fed independence as worth defending.

If this tactic succeeds, it establishes a precedent. Future Fed governors will know that angering the president carries prosecutorial risk. Current Fed Governor Lisa Cook, whose removal Trump is simultaneously challenging in court, would likely resign rather than fight both a legal battle over her tenure and potential prosecution. Potential future nominees would know that accepting a Fed position means accepting possible prosecution if the president disagrees with their decisions.

Within a few years, the Fed’s Board of Governors would transform from independent experts committed to the central bank’s statutory mandate into political appointees focused on keeping their jobs and staying on the president’s good side.

Republican Opposition to the Investigation

Senator Dave McCormick of Pennsylvania said the proper remedy was “Congressional oversight,” not prosecution. Representative French Hill, chair of the House Financial Services Committee, called Powell “a man of integrity” and characterized the investigation as “an unnecessary distraction” and warned it “could undermine this and future Administrations’ ability to make sound monetary policy decisions.”

Senate Majority Leader John Thune emphasized that “the central bank maintains its independence” and “I want to see them operate in an independent way, free of politics.” When pressed on whether he’d override the blockade, Thune declined to commit.

That refusal to commit is decisive. With the majority leader unwilling to ram through a nominee despite the opposition, and with visible concern about Fed independence, the position became nearly unassailable within his party.

Eleven central bank governors from around the world issued a joint statement declaring they stood “in full solidarity” with Powell and reaffirming that “the independence of central banks is a cornerstone of price, financial and economic stability.” The signatories included Christine Lagarde of the European Central Bank and Andrew Bailey of the Bank of England.

Central bankers avoid commenting on other nations’ domestic political affairs as a matter of protocol. That they broke protocol testified to how serious the international community perceived the threat to American financial governance.

What Happens If the Blockade Holds

Powell’s term as Fed Chair expires in May 2026. Trump has indicated Kevin Hassett, his National Economic Council director, is the leading candidate, though Kevin Warsh, a former Fed governor, has also been mentioned.

All leading candidates face the veto if nominated while the Powell investigation remains pending.

Prediction markets shifted dramatically after the investigation was announced. Warsh’s probability of becoming the next Fed chair rose from 33% to 39%, while Hassett’s fell from 58% to 33%. Traders were betting that the investigation had made confirmation more difficult, increasing the relative probability of a more moderate choice.

But even a moderate choice faces the same blockade if the investigation continues.

The Federal Reserve Act doesn’t allow a temporary chair the way other agencies do. If no new chair is confirmed, the oldest board member would lead instead. Powell can remain as a governor until his term expires in January 2028 if he chooses, effectively becoming the senior governor without the formal chair title.

This has never happened before in modern times. It would create genuine operational confusion about authority relationships and succession during any crisis requiring decisive action. The Federal Reserve oversees banks, sets financial rules, and runs the system that moves trillions of dollars daily. Running the Fed without a confirmed chair would create confusion about who’s in charge, which would damage trust in the institution.

Markets would begin to wonder whether the Fed could make consistent, reliable decisions. Whether political dysfunction had compromised the institution. Whether the dollar was backed by an independent central bank committed to price stability. These concerns would quickly become reflected in higher interest rates on Treasury debt, as investors demanded a risk premium for uncertainty.

Alternatively, Powell could resign entirely, signaling that political pressure had succeeded in forcing out the Fed chair. That precedent would chill future Fed independence more effectively than any formal rule change.

The Supreme Court and Presidential Power Over the Fed

This collision is happening against the backdrop of a Supreme Court reconsidering presidential power over independent agencies.

Days before the Powell investigation was announced, the Supreme Court agreed to hear arguments in Trump v. Cook, concerning whether Trump has the right to remove Fed Governor Lisa Cook based on unsubstantiated allegations of mortgage fraud. Lower courts blocked the removal, ruling that Cook couldn’t be dismissed without clear findings of cause under the statute.

The case raises fundamental questions about presidential power that the Republican-dominated Supreme Court appears willing to expand. In Trump v. Wilcox, decided in May 2025, the Court’s majority held that the Federal Reserve merited special constitutional protection due to its “distinct historical tradition.” But the reasoning was cryptic and possibly temporary, leaving genuine uncertainty about whether the justices would ultimately protect Fed independence or permit presidential subordination.

The Trump administration appears to believe the Constitution gives the president complete control over all executive agencies. Under this theory, the president must be able to fire anyone working in the executive branch, making the Federal Reserve Act’s requirement of serious wrongdoing for removal unconstitutional.

The current Supreme Court has moved significantly in this direction, permitting Trump to remove officials from the National Labor Relations Board and Merits Systems Protection Board despite statutory protections. If the Court applies the same logic to the Federal Reserve in the Cook case, the legal protections for Fed independence could disappear.

Such a ruling would leave only the political resistance of members like the North Carolina Republican standing between presidential control and Fed independence.

This legal uncertainty creates the environment where prosecution becomes particularly potent. Even if Powell can’t be convicted—if the charges would fail on appeal—the mere threat accomplishes the objective of pressuring him to resign. Using prosecution as a political weapon is what laws against politically motivated prosecution are meant to stop.

But those rules only work if career prosecutors and their supervisors enforce them fairly. The system fails when the attorney general and prosecutors are loyal to the president instead of the law.

How Senate Rules Create Individual Veto Power

The blockade reveals something fundamental about how American government works versus how civics textbooks describe it.

The Constitution establishes the Senate’s power to confirm appointments as a check on executive authority. But the Framers didn’t specify the mechanics of how that check would operate. Over time, Senate rules and traditions created ways for individual members to block nominees.

Blue slips. Committee blocks. Unanimous consent objections. Requirements for special votes to end debate. None of these appear in the Constitution. They’re rules and traditions built up over 235 years of Senate history. They transform what looks on paper like a simple majority vote into a complex negotiation where individual members can effectively veto presidential choices.

This system has benefits and costs. The benefit is that it prevents presidents from ramming through nominees over substantial opposition—it forces compromise and consensus-building. The cost is that it allows individual members to hold nominations hostage for reasons having nothing to do with the nominee’s qualifications.

The North Carolina Republican’s use of this power is unusual because he’s not blocking a nominee over home-state concerns or personal objections to the candidate. He’s blocking all potential nominees until the executive branch changes its behavior toward a current officeholder. The lawmaker is using his confirmation power to force the executive branch to change its behavior, not to block one person.

And it’s working, at least so far, because enough other members view the underlying issue as sufficiently important to support the blockade.

The North Carolina Republican himself framed it in stark terms: “If there were any remaining doubt whether advisers within the Trump Administration are pushing to end the independence of the Federal Reserve, there should now be none.” That statement shows what’s at stake: whether the Federal Reserve can stay independent.

How this ends will determine whether Senate confirmation powers can still stop presidents from abusing their power. Or whether presidents can now bypass those checks using prosecution threats and favorable court rulings.

Possible Outcomes

The DOJ could drop the investigation without Powell resigning. This would send the message that Senate resistance succeeded and that institutions can push back against being prosecuted for political reasons. But it would require Trump to accept a public defeat, which seems unlikely.

Powell could resign under the threat of prosecution. This would establish that prosecution is an effective tool for presidents to remove agency leaders they disagree with—a precedent future presidents would certainly exploit. And it would leave the Fed in exactly the leadership limbo the North Carolina Republican is trying to prevent.

The investigation could proceed to indictment and trial. This would let the courts decide if the charges are real, potentially stopping unfair prosecution by acquitting Powell. But it would also mean years of litigation with the Fed chair under indictment, which would damage trust in the Federal Reserve.

Powell could remain as Fed chair despite the investigation, creating a permanent cloud over Fed decision-making. Every interest rate decision would be questioned as possibly influenced by the legal threat.

Trump could try to change Senate rules so only 51 votes are needed to confirm Fed nominees. This would require eliminating the filibuster for Fed nominees, a move that would destroy the remaining informal rules limiting presidential power over hiring.

Trump could wait out the situation, betting that the North Carolina Republican will eventually agree to consider a nominee if Trump abandons the prosecution of Powell. This seems most likely, but it requires Trump to be patient, which he rarely is.

How this ends will show whether independent agencies can stay independent when presidents use prosecution as a weapon. Or whether presidents have become so powerful that only individual members using Senate rules can stop them.

That’s a fragile way to protect the Federal Reserve’s independence. But right now, it’s what we’ve got.
