Kash Patel, President Donald Trump's nominee for FBI director, and Sen. Amy Klobuchar had a tense exchange at Patel's confirmation hearing Wednesday on Capitol Hill.

Utah Sen. Mike Lee, who sits on the powerful Judiciary Committee and has backed his nomination, defended Patel from claims he would weaponize the agency against the president’s foes.

Kash Patel, President Donald Trump’s pick to lead the FBI, is insisting to deeply skeptical Democrats that he did not have an “enemies list” and that the bureau under his leadership would not seek retribution against the president’s adversaries or launch politically motivated investigations.
