Trump: Democratic oversight of my administration could amount to 'presidential harassment'

Speaking from the Oval Office, Trump again denied any collusion between his team and Russia when he was questioned about the investigative powers Democrats will assume come January.

"It's probably presidential harassment and we know how to handle that. I know how to handle that better than anybody," Trump said.

"There's been no collusion, after two years," he added.

Special counsel Robert Mueller has yet to issue a final determination on the extent of connections between the Trump campaign and the Kremlin during the 2016 election.

"You're talking about millions and millions and millions of dollars of wasted money," Trump said. "There's been absolutely no collusion. But there has been a lot of collusion by the Democrats, with Russia and a lot of other people that maybe they shouldn't have been dealing with, including very dishonest people."

He didn't detail what he meant.

This is a breaking story and will be updated.
