Mueller Report, page-57

"There was swift condemnation from some of Trump’s opponents in Washington. John Brennan, a former director of the CIA, tweeted: “Donald Trump’s press conference performance in Helsinki rises to & exceeds the threshold of ‘high crimes & misdemeanors.’ It was nothing short of treasonous. Not only were Trump’s comments imbecilic, he is wholly in the pocket of Putin.”

John McCain, chairman of the Senate armed services committee and a former Republican presidential nominee, said: “Today’s press conference in Helsinki was one of the most disgraceful performances by an American president in memory. The damage inflicted by President Trump’s naivety, egotism, false equivalence, and sympathy for autocrats is difficult to calculate.

But it is clear that the summit in Helsinki was a tragic mistake.”There was even a rebuke from the most senior elected Republican, House Speaker Paul Ryan, who said both the US intelligence community and the House intelligence committee concluded that Russia interfered in the election.“The president must appreciate that Russia is not our ally. There is no moral equivalence between the United States and Russia, which remains hostile to our most basic values and ideals,” he said. “The United States must be focused on holding Russia accountable and putting an end to its vile attacks on democracy.”
Chuck Schumer, the Democratic minority leader in the Senate, said: “In the entire history of our country, Americans have never seen a president of the United States support an American adversary the way President Trump has supported President Putin. “For the president of the United States to side with President Putin against American law enforcement, American defence officials, and American intelligence agencies is thoughtless, dangerous, and weak. The president is putting himself over our country.”

And Jeff Flake, a Republican senator from Arizona, tweeted: “I never thought I would see the day when our American President would stand on the stage with the Russian President and place blame on the United States for Russian aggression. This is shameful.”For his part, Putin acknowledged that he had wanted Trump to win the 2016 election but reiterated his denial of meddling. Speaking through an interpreter, he said: “We should be guided by facts. Can you name a single fact that would definitively prove collusion? This is utter nonsense. Just like the president recently mentioned.”
