Trump's comments come just days after Mueller indicted 12 Russian intelligence officers for hacking Democratic servers during the 2016 campaign.

“It was a clean campaign,” Trump said on Monday. “We won that race, and it’s a shame that there can be even a little bit of a cloud over it.”

Putin on Monday denied that his country interfered in the 2016 U.S. elections during his talks with Trump. The U.S. intelligence community previously determined that Russia interfered with U.S. elections.

On Monday, Trump said he has "confidence in both parties," referring to both the U.S. intelligence community and Putin.

Trump has refused to condemn Putin or Russia in the aftermath of the indictments, instead blaming the Obama administration and the Democratic National Committee for not doing more to stop the attacks.
