Two intelligence sources say the FBI agrees with the CIA assessment that Russia interfered in the U.S. election, in part to help Donald Trump, clearing up any confusion and other reporting that the agencies weren't in sync.
The entire intelligence community, in fact, is now in alignment that the hacks were partly motivated to try and install Trump as president. The FBI and others continue to say that Russia didn't actually think that was going to happen.
An intelligence source also notes that a memo went out from CIA Director John Brennan to the agency's workforce Friday. Intelligence chiefs, including Brennan, Director of National Intelligence James Clapper and FBI Director James Comey, met earlier this week, according to the memo, and, "There is strong consensus among us on the scope, nature and intent of Russian interference in our presidential election."
