President Donald Trump continued to tweet Tuesday about the NFL, urging owners to bar players from kneeling during the national anthem.

Trump brought up the topic for the fifth day in a row, dating to a speech to a crowd of supporters in Alabama on Friday night, when he referred to an NFL player making a gesture during The Star-Spangled Banner as a “son of a bitch.”

In response, more than 200 players knelt or sat on a bench or took other actions during the anthems at games Sunday.

Among his tweets Tuesday, Trump wrote: “The NFL has all sorts of rules and regulations. The only way out for them is to set a rule that you can’t kneel during our National Anthem!”

The NFL, for its part, was not all that eager to continue the back-and-forth with Trump.

“He’s exercising his freedom to speak,” league spokesman Joe Lockhart said on a conference call with reporters, “and I’m exercising my freedom not to react.”
