"Because today, the president of the United States took your side in a fight between you and the United States". As such, his extraordinary performance on Monday fueled criticism of his presidency from both the right and left.
In his latest Closer Look segment (embedded above), Late Night host Meyers first focused on some other "disastrous" moments from Trump's trip overseas, including his decision to walk in front of Queen Elizabeth II (a royal faux pas) at an event in the United Kingdom, and his incoherent answers to journalists' questions about Brexit.
Sure enough, critics and even some usually reliable defenders were quick to pounce.
Sen. Ben Sasse-R-Neb., told CBS "This Morning" that "the president isn't leading".
That anger was further fueled after Trump refused to back the USA intelligence community's assessment on Russian Federation, and instead, railed against the Federal Bureau of Investigation and his political opponents during his summit with Putin in Helsinki on Monday.
In the joint news conference on Monday that followed a day of discussions between the two leaders in Helsinki, Finland, Mr. Trump stood next to Putin and defended him in the face of the conclusion by all the US intelligence agencies that the Russian government directed cyberattacks on the Democratic Party and on the campaign of its 2016 nominee, Hillary Clinton. "He offered to have the people working on the case come and work with their investigators with respect to the 12 people", Trump said.
"The president must appreciate that Russian Federation is not our ally", said Republican House Speaker Paul Ryan.
Can it really be that hard to confront the Russian president?
Chuck Hagel, a former senator and defense secretary, said that Trump "failed America" in the press conference.
No CIA agent would have entertained an individual private talk with any Russian, Mr. Brennan said, because "that's just something we don't do". And Trump continues to reject Mueller's probe as a "witch hunt", despite the indictments of Russian hackers and intelligence officials.
Trump on a Democratic National Committee server: "You have groups that are wondering why the Federal Bureau of Investigation never took the server".
After a stormy North Atlantic Treaty Organisation summit in Brussels last week, Trump was accused by critics of prioritising his ties to Putin over the transatlantic alliance.
Putin looked serious but smirked when journalists asked Trump about Russian meddling in the U.S. presidential campaign.
Near the conclusion of the press conference, Mr Putin segued from a discussion on Syria to the World Cup that Russian Federation had just hosted.
Trump said he had confidence in both parties but added he would like to see the DNC hand over its server.
"He continued to maintain that it was illegal to annex it", Putin said of Trump's stance. Putin simply answered the question with a laugh.
"President Trump proved not only unable, but unwilling to stand up to Putin". To Russia hawks, even consideration of the proposal pointed to the success of Putin's efforts to shake the foundations of American democracy.
