Donald Trump flipped out at Reuters White House correspondent Jeff Mason on Thursday amid his first grilling since losing the U.S. presidential election.

Trump was being asked if he’d concede the election should the Electoral College vote for Biden in December.

“Don’t talk to me that way. You’re just a lightweight. Don’t talk to me that way. Don’t talk — I’m the President of the United States. Don’t ever talk to the president that way.”

I could look at this glorious visual forever. Resolute Desk > This Desk > Clipboard. Losing power is brutal. https://t.co/hKv7VOFHA7

This mini resolute desk will never not make me laugh.

No, it wasn't Photoshopped. It's real.

Nobody who knows that they are the President has to remind people by shouting it loudly at reporters.

Especially not while sitting at an itty bitty, teenie weenie little resolute desk. So small. pic.twitter.com/wMIbVzQEzC
