Incoming Acting Director of National Intelligence Richard Grenell, who previously served as the U.S. Ambassador to Germany, has been given a mandate in his new position: clean house.

To get the job done, Grenell is hiring staff with a history of finding abuse, specifically with the FISA court, inside the intelligence community.

CBS News reporter Catherine Herridge has the story.
