President Donald Trump ignited a firestorm on Capitol Hill following his first summit with Russian President Vladimir Putin.

The political salvos came from both sides of the aisle after Trump on Monday stopped far short of condemning Russian meddling in the 2016 US election and appeared to take Putin's denial at face value.

"My people came to me — Dan Coats came to me, some others — they said they think it's Russia," Trump said during a joint press conference with Putin, referring to the director of national intelligence. "I have President Putin. He just said it's not Russia. I will say this: I don't see any reason why it would be."

US intelligence agencies and officials, including Coats, have given a scathing assessment of Russia's actions and concluded it used cyberattacks and other means to meddle in the election. Just three days before the summit, the special counsel Robert Mueller also indicted a dozen Russian intelligent officers suspected of interfering with the election.

Trump later backtracked his comments, saying in a tweet that he had "GREAT confidence" in the US intelligence community. But to some lawmakers, his support came too little, too late.
