Republicans will be under pressure to address Trump’s desires to change how elections are run in the U.S., something he continues to promote despite his win in November.

Republicans plan to move quickly in their effort to overhaul the nation’s voting procedures, seeing an opportunity with control of the White House and both chambers of Congress to push through long-sought changes that include voter ID and proof-of-citizenship requirements.

While some GOP senators have indicated they are all-in for Donald Trump's picks, others have withheld support, for now, especially on some of his more controversial nominees.

There are roughly 1,200 positions in the federal government that require Senate confirmation. The first cabinet official was confirmed in 1789 when the Senate unanimously approved President George Washington’s nomination of Alexander Hamilton to be treasury secretary.

The fate of President-elect Donald Trump's Cabinet is still unclear after Republican senators spent much of December carefully dodging questions about Robert F. Kennedy Jr.'s views on vaccines, accusations of sexual misconduct against Pete Hegseth and Tulsi Gabbard's 2017 meeting with then-President Bashar Assad of Syria.
