President Donald Trump on Monday angrily tried to shut down CNN reporter Kaitlan Collins for trying to ask him a question about embattled Supreme Court nominee Brett Kavanaugh.

During a press conference about Trump's renegotiated trade deal with Canada and Mexico, Collins tried to squeeze in a question about Kavanaugh -- and Trump frantically tried to shut her down.

"Don't do that!" the president exclaimed. "Excuse me, do you have a question on trade?"

Nevertheless, Collins persisted.

"You've already answered several questions on trade..." Collins began.

"Don't do that, that's not nice!" Trump again interrupted.

The president then tried to get some other reporter to ask a question about his trade deal -- but Collins kept talking.

"You said the FBI should interview whomever they believe is appropriate," Collins said. "Does that include Julie Swetnick, the third accuser? And can you promise to release the full findings when they finish the report, Mr. President?"
