President-elect Donald Trump called for recess appointments on Sunday, pressuring candidates competing for Senate Majority Leader to fast-track the incoming administration’s position-filling process.

“Any Republican Senator seeking the coveted LEADERSHIP position in the United States Senate must agree to Recess Appointments,” Trump wrote on X. “We need positions filled IMMEDIATELY!”

The expedited process flows from the Recess Appointments clause of the Constitution, which allows a president to fill administrative vacancies when the Senate is not in session. Recess appointments also bypass the normal confirmation process that accompanies executive appointments.

As the Senate prepares for its new Republican-led majority, three senators — John Cornyn (R-Texas), Rick Scott (R-Florida), and John Thune (R-South Dakota) — have emerged as the likely candidates to fill the role currently held by Mitch McConnell (R-Kentucky). McConnell announced in February he would step down from his leadership role while he serves out the rest of his current term.

All three senators jumped at Trump’s behest following the post, voicing support for the fast-tracked process. Scott replied in agreement stating he “will do whatever it takes to get [Trump’s] nominations through as quickly as possible”.

Cornyn and Thune framed their eagerness to conform to Trump’s demand as party unity against Democrats. Thune wrote, “We must act quickly and decisively to get the president’s nominees in place as soon as possible, [and] all options are on the table to make that happen, including recess appointments”. Cornyn voiced his concerns over the possibility that Senate Democrats “blockade President [Trump’s] cabinet appointments”, stating that “[i]f they do, we will stay in session, including weekends, until they relent.”

Trump has not yet made an endorsement for the Majority Leader role, but many Trump-aligned Republicans have endorsed Scott in recent days, including tech-billionaire Elon Musk. However, recent reports suggest that some GOP senators have soured on Scott’s bid for the leadership position.

The Senate will vote to fill the seat on Wednesday.
