President Trump and Vice President Vance have every right — and every reason — to call out Republican senators who hide behind the so-called blue-slip tradition to block nominees for key executive positions, especially U.S. attorneys.

The effect is simple and damaging: Trump is denied the full exercise of his constitutional authority over the executive branch. Without aligned U.S. attorneys across the country’s 94 districts, the administration’s de-weaponization agenda stalls. In some cases, it collapses outright. So far, the Senate has advanced just 18 of the 50 U.S. attorneys nominated by the administration.

That is the real function of the blue slip. It is not institutionalism. It is careerism. It lets senators hide.

The blue slip is a Senate custom requiring the consent of both home-state senators before certain nominees — U.S. attorneys, judges, U.S. marshals — can advance to committee. In practice, it operates as a hack of the Constitution. The Senate’s role is advice and consent by the full body. The blue slip transfers that power to two senators, and often to just one, who can halt the process without explanation or accountability.

Majority Leader John Thune (R-S.D.) has insisted that the Republican Senate will not reconsider the practice despite the abysmal pace of confirmations. “There are many Republican senators — way more Republican senators who are interested in preserving that than those who aren’t,” he said. What he has not explained is why.

The answer is avoidance. The blue slip spares Republican senators from taking difficult votes. The fewer Trump-aligned U.S. attorneys brought to the floor, the fewer public positions senators must take. The blue slip allows them to kill nominations quietly rather than oppose them openly.

Despite years of rhetoric about party realignment, the Senate remains dominated by politicians hostile to Trump’s agenda. Some were forced out. Many more learned to mimic an America First accent without embracing America First policy. They do just enough to deter primary challengers while staying safely aligned with donors, lobbyists, and institutional power.

Forcing senators to vote up or down on Trump-aligned prosecutors like Alina Habba in New Jersey or Julianne Murray in Delaware — both of whom were serving as acting U.S. attorneys until the Senate ran out the clock — would expose those evasions. So the Senate stalled them instead.

I watched this play out firsthand during the failed confirmation of Ed Martin, Trump’s nominee for U.S. attorney in Washington, D.C. Because D.C. is not a state, the blue slip did not apply. Senate leadership attempted a different maneuver: delay until time expired.

When the base demanded a vote, Senator Thom Tillis (RINO-N.C.) stepped in and tanked Martin’s nomination outright. As a judiciary committee member, Tillis effectively wielded a one-man veto by shifting the committee balance back toward Democrats.

That decision carried consequences. Shortly afterward, Tillis opposed advancing the One Big Beautiful Bill Act in its existing form. Trump threatened a primary. Tillis burned through his remaining political capital and soon announced that he would not seek re-election.

Had Tillis been able to blue-slip Martin, he might have avoided that outcome.

That is the real function of the blue slip. It is not institutionalism. It is careerism. Cloaked in collegial language, it operates as a mutual defense pact among Republican senators to shield one another from accountability. It lets senators hide. A six-year Senate term has become a financial asset in a hyper-funded political system. Assets avoid risk. Votes create risk. Fewer votes mean greater protection.

Defenders of the blue slip claim it preserves the Senate’s unique institutional character. That argument belongs to another century. Today’s Senate is neither deliberative nor restrained. It lurches between performative hearings and massive spending bills, punctuated by social media sound bites. Any appeal to Jeffersonian dignity at this point borders on parody.

Notably, the blue slip never restrains Democrats. When Democrats want nominees confirmed, process does not stand in the way. For Republicans, the blue slip amounts to unilateral disarmament dressed up as principle.

Trump and Vance should keep attacking this practice publicly. The only antidote to procedural cowardice is exposure. Voters who support a mandate deserve to see whether their senators will carry it out — or hide behind tradition while returning to business as usual in Washington.

Even if Republican senators ultimately vote against these nominees, at least the votes would happen in the open. Accountability begins there.
