Outgoing CIA Chief John Brennan criticized President-elect Donald Trump for his controversial Twitter habit and for being naive about Russia.
“Mr. Trump has to understand that absolving Russia is a road that he needs to be very, very careful about moving down,” Brennan told Fox News.
According to The Associated press, Brennan added: “Now that he's going to have an opportunity to do something for our national security as opposed to talking and tweeting, he's going to have tremendous responsibility to make sure that U.S. and national security interests are protected.”
Brennan also warned that Trump's reputation for impulsiveness could be dangerous.

"Spontaneity is not something that protects national security interests," he said.
Brennan pointed specifically to a Trump tweet where the president-elect harshly criticized intelligence agencies for allegedly leaking to the media a dossier of several unsubstantiated claims about the Trump campaign written by a former British spy who was initially hired by a Republican -- and later retained by Democrats -- to uncover damaging information on him.
“Intelligence agencies should never have allowed this fake news to "leak" into the public. One last shot at me. Are we living in Nazi Germany?” Trump tweeted.
“What I do find outrageous is equating an intelligence community with Nazi Germany,” Brennan said in response, according to The Guardian. “I do take great umbrage at that, and there is no basis for Mr. Trump to point fingers at the intelligence community for leaking information that was already available publicly.”

In response to Brennan's critique of his social media use and knowledge of world affairs, Trump again took to Twitter.
Quoting the Fox News headline, "Outgoing CIA Chief, John Brennan, blasts Pres-Elect Trump on Russia threat. Does not fully understand," Trump wrote: “Oh really, couldn't do... much worse - just look at Syria (red line), Crimea, Ukraine and the build-up of Russian nukes. Not good!"
Trump then suggested Brennan leaked the dossier.
“Was this the leaker of Fake News?” Trump tweeted.
