(CNN) President Donald Trump intends to nominate Deputy Transportation Secretary Jeffrey Rosen to be the new deputy attorney general, the White House announced in a news release Tuesday.

Trump's announcement comes following the confirmation of new attorney general William Barr and as current deputy attorney general Rod Rosenstein prepares for his mid-March departure -- setting the stage for a new set of Department of Justice officials to oversee special counsel Robert Mueller's investigation. Rosenstein previously oversaw the probe after former Attorney General Jeff Sessions recused himself , and more recently former acting attorney general Matt Whitaker supervised Mueller.

Rosen was previously a senior partner at Chicago-based law firm Kirkland & Ellis, where he worked for nearly 30 years, according to the White House. He served as general counsel at the Transportation Department and in the Office of Management and Budget in the administration of President George W. Bush.

A Northwestern University and Harvard Law School alum, Rosen taught as an adjunct professor at Georgetown University Law Center and chaired the American Bar Association's Section of Administrative Law and Regulatory Practice, per the White House.

Barr praised Rosen, whom he has known for more than 20 years, as an experienced manager and litigator.
