The Senate has sent hundreds of nominations back to the White House, throwing their fate into limbo.

Senators sent back more than 270 nominations from the previous session on Thursday, which marked the official start of the 116th Congress. The list of nominations bounced back to the White House was printed in the Congressional Record, published Friday afternoon.

In addition to the more than 270 nominations, the Senate also returned scores of foreign service nominees who were not listed individually.

Trump and administration officials have repeatedly lamented the pace of confirmations on Capitol Hill.

Of 707 key positions that require Senate confirmation, Trump has gotten 434 confirmed, according to a tracker from the Partnership for Public Service and The Washington Post.

Scheduling a nomination vote is up to McConnell, but any senator can force him to eat up days of floor time before getting to a final vote.

Under the rules of the Senate, Trump has to renominate the picks in order to get them considered for confirmation during the new session of Congress. Though not a fatal decision, it will force senators to eat up precious time by sending them back through the committees before they can be brought to the floor for a final vote.

Roughly 70 judicial nominees were included as part of the picks sent back to the White House. Democrats pledged late last year that they would not sign off on including Trump's court picks in an end-of-Congress deal after similar agreements earned them fierce backlash from their progressive base.

Progressive outside groups praised the decision to kick the nominations back to Trump, saying Democrats "stood firm" in the escalating fight over court picks.

"Each of these nominees, if confirmed, would have received a lifetime seat on the federal courts and had a profound impact on the lives of Americans long after Donald Trump leaves the White House," said Marge Baker, the executive vice president for People for the American Way.
