Celtics NBA champion Al Horford's sister Anna calls out Nick Bosa's viral MAGA moment supporting Donald Trump

San Francisco 49ers defensive end Nick Bosa celebrated Sunday night's win by interrupting his teammates' postgame interview. Bosa, who has been outspoken in his support for Donald Trump, wore a "MAGA" cap and flashed it to the camera during NBC's live broadcast.

Anna Horford, the sister of NBA champion and Boston Celtics center Al Horford, shared her thoughts on Bosa's viral moment.

"Idk how his teammates of color can even look at him," Anna Horford wrote on X

Bosa has been critical of the left, including former 49ers quarterback Colin Kaepernick and his work on race, at one point referring to the quarterback as a "clown."

Nick Bosa refused to comment after postgame interview interruption

Nick Bosa stepped up to the podium after the San Francisco 49ers defeated the Dallas Cowboys in primetime on Sunday night. He wore a different hat from what he sported on the field while Brock Purdy, George Kittle and Isaac Guerendo were being interviewed in the live NBC broadcast.

Bosa walked up to the postgame interview and pointed to his MAGA hat. NBC sideline reporter Melissa Stark remained unfazed by the interruption and continued with her interview.

“Alright, Nick Bosa with a message there.”-Stark said on the live broadcast

Putting the hat on and running on the field appeared to be Bosa's endorsement of Trump just days away from the 2024 Presidential Election. After the game, the defensive end was asked about his political views and if he would like to discuss the decision to wear the hat.

But Bosa decided not to elaborate on his choice of hat.

“I’m not going to talk too much about it. But I think it’s an important time."-Bosa told reporters after the game

NBC chose to remove the interruption from their official social media post of the postgame interview.
