Rep. Mark Meadows (R-NC) resigned from Congress on March 30 to assume his new role as White House Chief of Staff for Pres. Donald Trump (R). Meadows replaces Mick Mulvaney, who had served as the acting White House Chief of Staff since January 2, 2019. Meadows’ first day in his new role is March 31.

Meadows was first elected to represent North Carolina’s 11th Congressional District in 2013. He was a member of the House Freedom Caucus and chaired the group at one time.

Meadows announced in December 2019 that he would not run for re-election in 2020. Trump announced Meadows as his pick for chief of staff in March 2020. Trump tweeted on March 7, “I am pleased to announce that Congressman Mark Meadows will become White House Chief of Staff. I have long known and worked with Mark, and the relationship is a very good one.”

As White House Chief of Staff, Meadows will lead the staff of the Executive Office of the President (EOP) and advise the president on policy issues. Meadows is the fourth White House Chief of Staff in the Trump Administration. He was preceded—before Mulvaney—by Reince Priebus, who served in the role from January to July 2017, and John Kelly, who filled the position from July 2017 to July 2018. Including Meadows, there have been 30 White House Chiefs of Staff since the position was created in 1946.
