Supporters of former President Trump and Americans dissatisfied with Joe Biden have turned the chant “Let’s Go Brandon!” into a massive social media viral trend that has shown up at sporting events, airports, memes, all the way to the former president’s Saturday rally in Iowa.

It started as a profane anti-Biden chant at college football games but went to a new level yesterday when President Biden got a visit from a Christmas troll Friday when a father participating in the annual White House NORAD Santa-tracking call used the phrase “Let’s Go Brandon,” the slangy stand-in for “F— Joe Biden.”

The dad, identified only as Jared from Oregon, wished the president and first lady Jill Biden a merry Christmas before adding the anti-Biden phrase at the end of his family’s portion of the call.

“Merry Christmas and let’s go Brandon,” the father said as he signed off.

“Let’s go Brandon, I agree,” Biden said without missing a beat.
