Paul Ryan - "There is no question that Russia interfered in our election and continues attempts to undermine democracy here and around the world," said Ryan, a Republican from Wisconsin, in a statement. "That is not just the finding of the American intelligence community but also the House Committee on Intelligence."
John Cornyn - "I don't know (whether) the President is trying to use some sort of carrots and stick approach with Putin but I believe the intelligence community," Cornyn told CNN, adding that the recent indictments from special counsel Robert Mueller's probe are "spot on."
John McCain - Sen. John McCain, an Arizona Republican who has consistently criticized the President, said Trump's comments were "one of the most disgraceful performances by an American president in memory."
Bob Corker - the President "made us look like a pushover" and that Putin was probably eating caviar on the plane home.
"I was very disappointed and saddened with the equivalency that he gave between them (the US intelligence agencies) and what Putin was saying," said Corker, a Tennessee Republican who is not seeking re-election.
Liz Cheney - "As a member of the House Armed Services Committee, I am deeply troubled by President Trump's defense of Putin against the intelligence agencies of the U.S. & his suggestion of moral equivalence between the U.S. and Russia. Russia poses a grave threat to our national security," said Rep. Liz Cheney, a Wyoming Republican
Trey Goudy - "I am confident former CIA Director and current Secretary of State Mike Pompeo, DNI Dan Coats, Ambassador Nikki Haley, FBI Director Chris Wray, Attorney General Jeff Sessions and others will be able to communicate to the President it is possible to conclude Russia interfered with our election in 2016 without delegitimizing his electoral success," Gowdy said in a statement.
Lindsey Graham - "Missed opportunity by President Trump to firmly hold Russia accountable for 2016 meddling and deliver a strong warning regarding future elections," Graham tweeted. "This answer by President Trump will be seen by Russia as a sign of weakness and create far more problems than it solves."
Jeff Flake - "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," tweeted Flake, who is not running for re-election.
Elizabeth Warren - "Once again, @realDonaldTrump takes to the international stage to embarrass America, undermine our institutions, weaken our alliances, & embrace a dictator. Russia interfered in our elections & attacked our democracy. Putin must be held accountable -- not rewarded. Disgraceful," Warren tweeted.
Tim Kaine - "This is a sad, shameful moment for our great nation. We will reclaim our values and reassert our global leadership. We'll turn the page on this dark chapter. But it won't happen on its own. We all must stand up—to side with U.S. law enforcement and to protect all Americans," Kaine said.
