Mark Meadows resigns from Congress to become Trump's chief of staff

Rep. Mark Meadows officially resigned from Congress on Monday, ahead of becoming the new White House chief of staff.

The big picture: Meadows announced last year his retirement from Congress and was named by President Trump as Mick Mulvaney's replacement earlier this month. Per Axios' Alayna Treene, Meadows has been actively preparing for the role during the transition period and has been working closely with Mulvaney. Alayna reported Sunday that he would formally start as Trump's new chief on Tuesday.
