(CNN) President Donald Trump said Tuesday that Democratic attempts at oversight in the coming Congress 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.

Trump has used the term "presidential harassment" multiple times in the past to refer to the investigation into Russian interference in the 2016 election and potential collusion between the Trump campaign and the Russian government. He's also used the term to refer to Democratic criticism of his administration and potential tough oversight from the incoming Democratic-controlled House.
