President Trump has launched a petition to pressure the NFL into ordering players to stand for the national anthem — and urged his supporters to sign it.

“The president has asked for a list of supporters who stand for the National Anthem. Add your name below to show your patriotism and support,” said the petition issued by the Trump Make America Great Again Committee, a Trump/Pence fund-raising outfit.

The petition is also available on the Republican National Committee’s Web site.

Players kneeling during “The Star-Spangled Banner” say they are protesting the police killings of unarmed blacks across the US, as well as racism in the country’s criminal-justice system.

But Trump says they are showing hostility to the flag, the country and US troops.

NFL Commissioner Roger Goodell said Wednesday that the league believes “everyone should stand for the national anthem” but would not change its policies to force players to do so.
