President Donald Trump criticized some in the National Football League Friday night at a rally for Alabama Republican Senate candidate Luther Strange , saying team owners should fire players for taking a knee during the national anthem.
Trump added that if fans would "leave the stadium" when players kneel in protest during the national anthem, "I guarantee, things will stop."
Trump said NFL owners should respond to the players by saying, "Get that son of a b**** off the field right now, he's fired. He's fired!"
"For a week, (that owner would) be the most popular person in this country. Because that's a total disrespect of our heritage. That's a total disrespect for everything we stand for," Trump said.
Last year, Colin Kaepernick -- formerly with the San Francisco 49ers, but currently without a team -- drew national attention for refusing to stand during "The Star-Spangled Banner" prior to kickoff.
"I am not going to stand up to show pride in a flag for a country that oppresses black people and people of color," Kaepernick told NFL Media in August 2016.
His protest spurred both support and backlash.
Following the events in Charlottesville, Virginia, where white supremacists gathered to protest the removal of a Confederate soldier statue, Seattle Seahawks defensive end Michael Bennett told CNN he would follow suit.
"I can't stand for the national anthem," Bennett said. "I can't stand right now. I'm not going to be standing until I see the equality and freedom."
Trump also took aim at NFL efforts to prevent concussions. "They're ruining the game, right?" he said. "They're ruining the game."
