Several key U.S. Department of Justice leadership positions remain vacant six months into President Joe Biden's term, potentially delaying key decisions and initiatives on a range of policy and enforcement issues.

Just four of the 15 Senate-confirmed positions at Main Justice are currently in place. Seven more nominees are awaiting Senate approval. Delays in approving personnel are not unusual at the start of a new administration, but experts said a lack of permanent officials could prevent key Biden administration priorities, like ramping up antitrust and corporate enforcement, from immediately getting off the ground.
