President Donald Trump says football players can protest during a game "but they cannot do it during the national anthem."
Trump says there are plenty of other places where players can protest.
Trump says that when players kneel during the anthem "they're not respecting our country." NFL players have been kneeling during "The Star-Spangled Banner" to protest racial injustice. Trump has been criticizing players who take a knee since a rally last week in Alabama.
Addressing reporters at the White House on Wednesday before a trip to Indiana, Trump says the NFL is in a very "bad box" over the issue.
He says the NFL has to change or business is "going to go to hell."
President Donald Trump says he has spoken to Dallas Cowboys owner Jerry Jones amid his extended attacks on NFL players for kneeling during the national anthem.
On Twitter Wednesday, Trump says the two spoke Tuesday. He says: "Jerry is a winner who knows how to get things done. Players will stand for Country!"
On Monday night, Jones - a supporter of Trump - and his players knelt, arm-in-arm, before the anthem, then rose for the playing of the song ahead of the team's victory at the Arizona Cardinals.
Trump has spent days lashing out at players who kneel, a practice that started with a handful of players to protest racial issues, including police brutality.
Responding to Trump, hundreds of players have been sitting, kneeling, locking arms or remaining in locker rooms.
