Sen. Chuck Grassley (R-IA) expressed criticism over FBI Director Christopher Wray’s leadership of the agency, calling for “a new course” to be charted by the agency going forward.

Grassley’s comment comes a day after President-elect Donald Trump nominated Kash Patel to serve as his next FBI director, prompting questions over what the future holds for Wray leading the FBI. FBI directors typically serve 10 years at a time, and some called for Wray to continue working his job.
