NFL players aren’t the only ones “taking a knee” in protest of President Donald Trump. A number of high profile musicians, Pharrell Williams, John Legend and Eddie Vedder, have decided to show solidarity with their athletic brothers.

“If I want to get on my knees right now for the people of my city, for the people of my state, that’s what this flag is for,” Williams told the crowd on Sunday at the Concert for Charlottesville, before get down on two knees in support of NFL players’ right to take a knee in protest during the American national anthem.

The growing protests have come after Trump blasted NFL players, including former San Francisco 49ers quarterback Colin Kaepernick, for kneeling during the national anthem as a silent protest against the treatment and killing of African-American people by police.

“Wouldn’t you love to see one of these NFL owners when somebody disrespects our flag to say, ‘Get that son of a b**ch off the field right now’?” Trump asked a crowd at a rally in Alabama on Friday.

Those comments set off a wave of protests by NFL players at games on Sunday, as well as comments and shows of support by other athletes, artists and celebrities throughout the weekend.

So much so that according to analytics firm Talkwalker, there were more than 4 million social posts related to the NFL and the national anthem, including those using the hashtags #TakeAKnee or #TakeTheKnee.

On Sunday alone, there were 2.5 million tweets using the same hashtags, with volume on the social media site spiking between 1-2 pm ET with 240,000 tweets on the topic.

The hashtags #BoycottNFL and #MAGA were also trending with 101,500 and 90,900 mentions respectively as of Monday, Sept 25 at 8 am ET.
