Outgoing acting U.S. Attorney for the District of Columbia Ed Martin said Tuesday the Department of Justice is reviewing several of former President Joe Biden’s final-hour pardons, vowing that his new office will scrutinize whether clemency was used “correctly” or politically.

Martin, whose nomination to the Washington, D.C., prosecutor post collapsed last week after key Senate Republicans pulled support, confirmed that President Donald Trump has reassigned him to two new high-profile roles: Director of the Office of the Pardon Attorney and head of the DOJ’s recently established Weaponization Working Group.
