Hip-hop artist Jay-Z threw his support behind NFL players kneeling during the national anthem during his performance on NBC’s “Saturday Night Live.”

While performing his song “Bam” with Damian Marley, Jay-Z wore a custom jersey featuring the name and number of NFL quarterback Colin Kaepernick.

Jay-Z’s symbolic attire comes after President Trump’s repeated criticism of NFL players, including Kaepernick, who don’t stand during the playing of the national anthem.

{mosads}Last weekend Trump launched a series of tweets calling for NFL owners to fire players who take a knee and urging the NFL to implement a rule banning players from kneeling during the anthem, just a few days after he referred to players who don’t stand as “sons of bitches” during a rally in Alabama.

NFL players and owners responded in force last Sunday, with dozens of players kneeling or linking arms as the anthem played. Three teams remained in the locker room during the anthem, and several NFL owners joined their teams on the field during the demonstrations.

Trump has previously attacked Kaepernick for kneeling during the national anthem to protest the treatment of people of color in America, and suggested Kaepernick was still a free agent because he wouldn’t stand for the anthem.

Trump has continued to call for an end to the protests, tweeting Saturday it was “very important” for NFL players to stand during the anthem.
