President Trump’s push to keep NFL players who don’t stand during the national anthem a major storyline continued on Monday morning.

Players from the Giants, Seahawks and 49ers did not stand for the anthem before Sunday’s games and the President took note of it as well as the fact that the league has not bowed to his call to change the rules to force players to stand during the playing of the song. As you could probably guess, the President chose Twitter as the medium for his message.
