After President Donald Trump and Russian Prime Minister Vladimir Putin's historic joint press conference in Helsinki this afternoon, a few strong words began to circulate on Twitter: "indefensible," "puppet," and "treasonous," for example.

If those words haven't given you an ulcer yet, consider what CNN's Anderson Cooper had to say at the close of the pair's joint remarks.

"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," Cooper told viewers.

He's not wrong. Between Trump's refusal to criticize Putin and his denial of the findings of his own intelligence agencies, the entire conference was jaw-dropping, even by Trump standards.

Thanks to Cooper for properly summing it up.
