Here are some key reactions to the press conference, broken down by party:

REPUBLICANS

• “The president must appreciate that Russia is not our ally,” House Speaker Paul Ryan said in a statement. “There is no moral equivalence between the United States and Russia, which remains hostile to our most basic values and ideals.”

• “Russia interfered in the 2016 election,” Sen. Orrin Hatch (R-Utah) said in a statement. “Our nation’s top intelligence agencies all agree on that point. From the President on down, we must do everything in our power to protect our democracy by securing future elections from foreign influence and interference, regardless of what Vladimir Putin or any other Russian operative says.”

• “I think [Putin] gained a tremendous amount,” Sen. Bob Corker (R-Tenn.), ranking member of the Senate Foreign Relations Committee, told reporters. “I would guess he’s having caviar right now.”

• “President Trump failed America today,” Chuck Hagel, a former GOP senator, said on CNN. “He failed America, our interests, in every way.”

• “That’s how a press conference sounds when an Asset stands next to his Handler,” former RNC Chairman Michael Steele 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,” Sen. Jeff Flake (R-Ariz.) tweeted. “This is shameful.”

• “I strongly disagree w/ statement that Russia did not meddle in 2016 election,” Rep. Frank LoBiondo (R-N.J.) tweeted. “With all I have seen on House Intel Comm & additional indictments of 12 Russian officers last week, it is clear Russia’s intentions. President Trump missed opportunity to hold Putin publicly accountable.”

• “Missed opportunity by President Trump to firmly hold Russia accountable for 2016 meddling and deliver a strong warning regarding future elections,” Sen. Lindsey Graham (R-S.C.) tweeted. “This answer by President Trump will be seen by Russia as a sign of weakness and create far more problems than it solves.

“It is imperative that Congress hold hearings on the extent and scope of any cooperation with Russia in Syria regarding Iran’s presence,” he continued.

• “A person can be in favor of improving relations with Russia, in favor of meeting with Putin, and still think something is not right here,” Rep. Justin Amash (R-Mich.) tweeted.

• “This is bizarre and flat-out wrong,” Sen. Ben Sasse (R-Neb.) said in a statement. “The United States is not to blame. ... When the President plays these moral equivalence games, he gives Putin a propaganda win he desperately needs.

Not every response was critical.

• “Glad to hear it,” Sen. Rand Paul (R-Ky.) tweeted in response to a video of Trump saying he would “put world peace ahead of politics.”

DEMOCRATS

• “Every single day, I find myself asking: what do the Russians have on @realDonaldTrump personally, financially, & politically?” House Minority Leader Nancy Pelosi tweeted. “The answer to that question is that only thing that explains his behavior & his refusal to stand up to Putin. #ABetterDeal”

• “For the president of the United States to side with President Putin against American law enforcement, American defense officials, and American intelligence agencies is thoughtless, dangerous, and weak,” Senate Minority Leader Chuck Schumer tweeted. “The president is putting himself over our country.

“A single, ominous question now hangs over the White House: what could possibly cause @realDonaldTrump to put the interests of Russia over those of the United States[?]” he continued.

• “Russia interfered in our elections and they will do it again unless we stand up to Putin,” Sen. Chris Van Hollen (D-Md.) tweeted. “It’s insane that the President of the United States is attacking the FBI and believes Putin over his own intelligence officials and evidence presented by both the House and the Senate. Wow.”

• “That press conference was a disgrace,” Rep. Eliot Engel (D-N.Y.), ranking member of the House Foreign Affairs Committee, said in a statement. “The President has just committed a shocking betrayal of his duties: dismissing Russia’s attack on American democracy while standing on foreign soil next to America’s chief adversary. He accepted the brazen lies of Vladimir Putin over the unanimous conclusions of America’s intelligence and law enforcement communities.”

• “President Trump just attacked our intelligence agencies and law enforcement for doing their jobs while standing next to a dictator who intervened in our election to help elect Trump,” Rep. Adam Schiff (D-Calif.) tweeted. “Putin will take this as a green light to interfere in 2018, and it is. Cowardly and shameful.”

• “Once again, @realDonaldTrump takes to the international stage to embarrass America, undermine our institutions, weaken our alliances, & embrace a dictator,” Sen. Elizabeth Warren (D-Mass.) tweeted. “Russia interfered in our elections & attacked our democracy. Putin must be held accountable – not rewarded. Disgraceful.”

• “This is a sad, shameful moment for our great nation,” Sen. Tim Kaine (D-Va.) tweeted. “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.”

• “This entire trip has just been one giant middle finger from President Trump to his own country,” Sen. Chris Murphy (D-Conn.) tweeted. “Just jaw dropping.”

• “It’s embarrassing that American flags were present at #TrumpPutinSummit, because an American president was not,” Rep. Eric Swalwell (D-Calif.) tweeted. “Our president, above everything else, must defend US. @realDonaldTrump just showed he cannot and will always side with Russia. @HouseGOP, do you hear the fire alarm?”

• “The president’s refusal to acknowledge that Putin interfered in our elections should alarm us all,” Sen. Bill Nelson (D-Fla.) tweeted. “Putin is a threat to our democracy and our upcoming election, that’s a fact. The president’s unwillingness to stand up to him and defend our nation is unacceptable and embarrassing.”

• “In all fairness to @realDonaldTrump, performance reviews with your boss are often 1 on 1,” Rep. Nita Lowey (D-N.Y.) tweeted.

• Trump “didn’t hold Putin responsible, & he didn’t say one negative word about Putin & his attack against our country,” Rep. Ted Deutch (D-Fla.), ranking member of the House Ethics Committee, tweeted. “Our President likes to talk tough, but when it came time to take a strong stand on behalf of the US, he completely and utterly failed.”

• Trump “lets Putin lie to his face and doesn’t even contradict him,” Sen. Ron Wyden (D-Ore.), ranking member of the Senate Finance Committee, tweeted. “Cannot remember a more blatant display of weakness by a U.S. president.”

• “President Trump’s press conference with Putin was an embarrassing spectacle,” Sen. Bernie Sanders (I-Vt.), who ran for president as a Democrat in 2016, tweeted. “Rather than make clear that interference in our elections is unacceptable, Trump instead accepted Putin’s denials and cast doubt on the conclusions of our intelligence community. This is not normal.”

• “Donald Trump’s press conference performance in Helsinki rises to & exceeds the threshold of ‘high crimes & misdemeanors,’” former CIA Director John Brennan, who served under Democratic President Barack Obama, tweeted. “It was nothing short of treasonous. Not only were Trump’s comments imbecilic, he is wholly in the pocket of Putin. Republican Patriots: Where are you???”
