The Justice Department has dropped its criminal investigation into Federal Reserve Chairman Jerome Powell, clearing the way for President Donald Trump’s pick to replace him to be confirmed by the Senate.

The DOJ announced on Friday that it was ending the inquiry. The news marks the end of a contentious period in which Sen. Thom Tillis (R-NC), a member of the Senate Banking, Housing, and Urban Affairs Committee, was threatening to block Trump nominee Kevin Warsh from a confirmation vote.
