Why are NFL players protesting?
Last year, San Francisco 49ers quarterback Colin Kaepernick started kneeling during the national anthem to highlight alleged police brutality cases against black Americans.
Since then, more football players have started taking a knee.
Trump has condemned this form of protest, saying it's disrespectful to the American flag and military veterans.
He has called for an NFL boycott and urged teams to fire protesting players.

"While everyone is entitled to their own opinions, I don't think it's too much to ask NFL players to respect the flag," Pence said in a statement.
Trump tweeted that he had asked Pence to leave if the players kneeled.
