WASHINGTON (AP) — President-elect Donald Trump’s pick to lead the CIA told senators during his confirmation hearing Wednesday that the nation’s premier spy agency must do a better job of staying ahead of global threats posed by Russia, China and other adversaries.

The former Texas congressman said the CIA needed to return to its core missions following criticism from Donald Trump the agency was politically biased.

Trump’s nominee for CIA director vowed a more muscular approach to stealing adversaries’ secrets and pledged not to politicize spy agency.
