Jeffrey Rosen has spent the first two years of the Trump presidency in a quiet corner of a tumultuous administration, serving as second-in-charge of a U.S. Transportation Department he first came to know in 2003 when he became the agency’s general counsel.

Rosen is now the Trump administration’s pick for U.S. deputy attorney general, a position that would elevate his national prominence and put him in the spotlight as part of the team overseeing the special counsel’s Russia investigation.
