Ex-CIA head says Trump remarks on Russia interference 'disgraceful'

Former CIA director John Brennan testifies before the House Intelligence Committee to take questions on “Russian active measures during the 2016 election campaign” in the U.S. Capitol in Washington, U.S., May 23, 2017.

Former CIA director John Brennan on Friday criticized as "disgraceful" President Donald Trump's efforts to play down U.S. intelligence agencies' assessment that Russia meddled in the 2016 U.S. election.

Trump's administration has been dogged by investigations into allegations of Russian interference in last year's U.S. presidential election and possible ties with his campaign team.
