President Trump on Monday criticized the number of National Football League players who kneeled during the national anthem during games across the league Sunday.

"Two dozen NFL players continue to kneel during the National Anthem, showing total disrespect to our Flag & Country. No leadership in NFL!" Trump tweeted Monday morning.

Protests over police brutality against blacks and racial injustice have continued across the NFL since the season started nearly two months ago.

This past weekend, one-third of the 400 off-duty police officers who had been expected to work the Miami Dolphins game against the New York Jets refused to do so because of the league's handling of the protests.
