President Donald Trump late Tuesday announced his intention to nominate Jeffrey Rosen to serve as the Justice Department's new deputy attorney general.

The big picture: Rosen, who is currently deputy transportation secretary and has previously been confirmed by the Senate, will replace Rod Rosenstein, who is reportedly expected to step down by mid-March. Rosen previously worked for nearly 30 years at the law firm Kirkland & Ellis, where recently-confirmed Attorney General William Barr also worked prior to his nomination.
