President Trump on Tuesday said he intended to nominate Jeffrey Rosen to be the next deputy attorney general.
Rosen is currently deputy Transportation secretary and oversees the department's day-to-day operations.
He also served as general counsel and a senior policy advisor at the White House Office of Management and Budget from 2006 to 2009.
Rosen previously worked as a senior partner at Kirkland & Ellis LLP — the same law firm as the new attorney general, William Barr.
The current deputy attorney general, Rod Rosenstein, is expected to leave his post in March. His departure had been expected after Barr was confirmed last week.
Rosenstein has overseen special counsel Robert S. Mueller III's investigation since then-Atty. Gen. Jeff Sessions recused himself. Barr now oversees the remaining work in the Russia investigation.
