CNN's Anderson Cooper reacted to President Trump's remarks at a joint news conference with Russian President Vladimir Putin shortly after they ended.

"You have been watching perhaps one of the most disgraceful performances by an American president at a summit in front of a Russian leader certainly that I've ever seen. An extraordinary press conference."

Trump, at the news conference, said he didn't see a reason for Russia hacking into the 2016 presidential election.

Cooper said Trump was given the chance the opportunity to give a statement on election interference, and "he blinked."
