Prior to last night's Monday Night Football game between the Dallas Cowboys and Arizona Cardinals, the entire Cowboys roster, including team owner Jerry Jones, locked arms and took a knee on the field right before the playing of the national anthem.

The Cowboys and Cardinals game wrapped up Week 3 of the NFL in which teams across the league kneeled, locked arms, or refused to go on the field altogether during the national anthem, as a show of unity in the wake of President Trump's comments about protesters. 

Trump has called on owners to fire the "son of a bitch" players who kneel during the anthem, and he has now called on NFL commissioner Roger Goodell to institute a rule outlawing players from kneeling.

During last night's Monday Night Football broadcast, Trump sent several tweets regarding the anthem protests, including: 

"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 booing at the NFL football game last night, when the entire Dallas team dropped to its knees, was loudest I have ever heard. Great anger"
