Former San Francisco 49ers quarterback Colin Kaepernick expressed his appreciation for Eminem's fiery four-and-a-half-minute freestyle takedown of President Trump.

"I appreciate you," Kaepernick said in a tweet that also had the video, which aired at the 2017 BET Hip Hop Awards on Tuesday.

Kaepernick led a movement beginning last season when he took a knee during the national anthem to protest the treatment of African Americans and other minorities in the U.S. Eminem dedicated a portion of his freestyle to supporting Kaepernick and other NFL players who have recently come under attack by the president for those demonstrations.

"Now, if you're a black athlete, you're a spoiled little brat for tryna use your platform or your stature," Eminem said.

The rapper noted that Trump's tweets and comments on the NFL are a distraction from important issues like hurricane-ravaged Puerto Rico or gun reform in the wake of the Las Vegas mass shooting.

"This is his form of distraction. Plus, he gets an enormous reaction. When he attacks the NFL, so we focus on that, instead of talking about Puerto Rico or gun reform for Nevada. All of these horrible tragedies and he's bored and would rather cause a Twitter storm with the Packers," Eminem said.

For Kaepernick, who is currently not employed in the NFL, Eminem raised his fist.

"This is for Colin, ball up a fist," he said. "And keep that shit balled like Donald the bitch."

Other rappers, celebrities, and journalists praised the performance by Eminem, whose real name is Marshall Mathers. Included in that list is NBA star Lebron James, who tweeted a raised fist and said racism is all Trump is "fantastic for," which was part of a verse in Eminem's rap.
