A caller has pranked President Joe Biden by dropping anti-Biden “Let’s go, Brandon” taunt into their chat during a White House Christmas event.

President Biden and First Lady Jill Biden were hosting the festive call for families when a father told the president: “Let’s go, Brandon.”

Apparently unaware of the gibe, President Biden said he agreed.

The term, which has become a rallying cry for many conservatives, is code for a profane insult directed at Joe Biden.

The first couple were speaking virtually with children for a White House custom, tracking the journey of Santa’s sleigh via the North American Aerospace Defense Command.

During Christmas Eve’s event in the South Court Auditorium of the executive mansion, the Bidens spoke with a family from Oregon: Griffin, 11, Hunter, three, Piper, four, Penelope, two, and their father, Jared.

“I assume you’re dad,” the president said.

“Hi. Yes sir,” replied Jared.

“OK, Dad, what do you want for Christmas?” asked Presidnet Biden.

“Maybe a quiet night,” he replied laughing.

The president said: “You know, Dad, we have a Hunter, too. We have a son named Hunter and a grandson named Hunter.”

“I didn’t know you had a grandson named Hunter, that’s cool,” said Jared.

The president asked how old was Griffin.

“I’m 11,” Griffin said. He said he wanted a piano.

Jared interjected: “I was going to say he has to cut some trees down to get a piano!”

Hunter wanted a Nintendo Switch, Piper wanted a Barbie.

The president reminded the children to be in bed by nine o’clock otherwise Santa might not show up.

The first lady said: “Have a merry Christmas, have a wonderful Christmas.”

President Biden told Jared: “I hope you have a wonderful Christmas.”

The father replied: “Yeah, I hope you guys have a wonderful Christmas as well. Merry Christmas and let’s go, Brandon.”

The president replied: “Let’s go, Brandon. I agree.”

There was silence.

President Biden added: “Hey, by the way, are you in Oregon? Where’s your home? I think we lost him.”

According to a recent Gallup poll, only 5% of voters who identify as Republican currently approve of the president’s performance.

That same poll shows President Biden’s overall approval rating has dipped to 43%.

How did ‘Let’s go, Brandon’ start?

It all began at the end of a televised Nascar stock car race in Talladega, Alabama, on October 2. NBC reporter Kelli Stavast was interviewing the winner, driver Brandon Brown, when members of the crowd in the grandstand behind them began chanting an obscenity directed at the president.

It was clearly picked up on the broadcast’s audio.

Whether by mistake or as an attempt to deflect from the swearing on live television, Kelli Stavast told Brandon Brown the crowd was cheering him on with chants of “Let’s go, Brandon.”

A meme was born.
