The top Democrat on the Senate Intelligence Committee criticized President Trump following his face-to-face meeting with Russian President Vladimir Putin, saying he did not do enough to challenge Russian meddling in the election last year.

“We are told President Trump raised the subject of Russian interference in our 2016 presidential election,” Sen. Mark Warner, D-Va., said in a Friday statement, hours after the two leaders met for roughly two hours in Hamburg, Germany, during the G-20 summit meeting.
