The National Football League will air a televised advertisement promoting franchise unity on Sunday in the face of a barrage of attacks from President Trump.

"We think this is the single best response to demonstrate what we are about," a spokesman for the league told CNN, which first reported the news. "It stands in stark contrast to some who practice the politics of division."

The ad, which was originally produced for the Super Bowl, is titled "Inside These Lines," and is narrated by actor Forest Whitaker.

The NFL told CNN the piece is meant to "demonstrate the power of football to bring people together."

News of the ad comes as the NFL community defends itself from the president, who has taken to attacking the league this weekend for allowing players to kneel, rather than stand, during the national anthem.

"Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, to say, 'Get that son of a b---- off the field right now. He is fired,'" Trump said at a Senate campaign rally in Alabama on Friday.

The president continued his attacks on the league on Sunday, saying players who kneel during the anthem should be fired or suspended.

Members of the NFL community have condemned Trump's remarks. NFL commissioner Roger Goodell labeled the comments as "divisive."

Players for the Baltimore Ravens and the Jacksonville Jaguars, including the owners, put on a show of unity on Sunday, kneeling and linking arms during the national anthem before a game in London.
