President Donald Trump took note when various NFL teams engaged in multiple forms of protest during the national anthem in Week 3.

Trump tweeted halfway through the early block of games Sunday, stating that he finds locking arms acceptable but remains opposed to players kneeling.

Great solidarity for our National Anthem and for our Country. Standing with locked arms is good, kneeling is not acceptable. Bad ratings! — Donald J. Trump (@realDonaldTrump) September 24, 2017

On Friday, Trump called for NFL owners to fire any player that "disrespects" the flag. Players, coaches, and owners have since spoken out against the president's remarks.
