PHOENIX, Arizona - Dallas Cowboys owner Jerry Jones and his team knelt prior to the national anthem Monday night as a sign of solidarity with the rest of the NFL, capping off a weekend defined by symbolic protests against President Trump.

The primetime Monday Night Football matchup between the Cowboys and Arizona Cardinals at the University of Phoenix Stadium was the last game on the NFL's schedule for the third week of the season following Mr. Trump's comments on Friday, when he suggested owners should fire players who kneel during the national anthem.  

Tuesday morning, President Trump reacted.

On Monday night, Jerry Jones, a known Trump supporter, linked arms and took a knee with the Cowboys for nearly 20 seconds before the national anthem, drawing ire from the home crowd in Arizona who profusely booed the team. During singer Jordin Sparks' rendition of the anthem, the Cowboys stood up while the Cardinals players interlocked arms with members of the military. 

Before the game, Dallas Cowboys executive vice president Charlotte Jones Anderson told ESPN's Lisa Salters the team would take a knee as "a statement on equality and representation of unity" but the "players were adamant about separating that message from the national anthem."  

The White House on Monday defended President Trump's criticism of players who don't stand up for the anthem.
