WATCH: Trump Tells Biden Politics Is 'Not A Very Nice World' As They Meet At White House For First Time Since Election

President-elect Donald Trump met with President Joe Biden at the White House in order to discuss the transition of power between the two administrations.

The President-elect, who emerged victorious on election day in November, met with the incumbent President on Wednesday and thanked him for his cooperation.

The visit is a traditional ritual to symbolize the peaceful transition of power but Trump refused to take part four years ago after he made baseless claims of a stolen election.

"Thank you very much. And politics is tough. And it's in many cases not a very nice world, but it is a nice world today and I appreciate it very much," said Trump. "A transition that is so smooth, it will be as smooth as it can get, and I very much appreciate that."

First lady Jill Biden was there to greet Trump. She gave him a handwritten letter for Melania Trump, who did not attend the event.
