A new petition released on the Republican National Committee website is asking for the signatures of Trump supporters who stand for the national anthem, one day after the president reignited his attacks against the NFL on Twitter.
"The President has asked for a list of supporters who stand for the National Anthem," the petition reads. "Add your name below to show your patriotism and support."
The petition was emailed to Trump supporters, according to the New York Daily News.
Fine print at the bottom of the petition shows it was paid for by the Trump Make America Great Again Committee, a fundraising committee operated by the Trump campaign and the RNC.
The petition was released Oct. 19, one day after Trump posted tweets criticizing the NFL's recent decision not to force players to stand during the national anthem.
"The NFL has decided that it will not force players to stand for the playing of our National Anthem. Total disrespect for our great country!" Trump tweeted.
The president followed up with a second tweet directed at the NFL, saying the organization is "too much talk, not enough action."
After an Oct. 18 meeting with team owners, NFL Commissioner Roger Goodell announced that the league would like to see players stand for the national anthem, but there will be no penalties for those who take a knee.
"I think our clubs all see this the same way -- we want our players to stand, we're going to encourage them to stand and we're going to continue to work on these issues in the community," Goodell told reporters, according to the NFL. "We'll address issues -- I can't deal with hypotheticals right now, we'll deal with those issues if they come up -- but for right now, that's our focus."
Trump set off a wave of protest across the NFL after he called for players who kneel to be fired, saying owners should "get that son of a b***h off the field" during a September rally.
On Twitter, Trump said the league should force players to stand and fans should boycott the league until the rule changes.
"If NFL fans refuse to go to game until players stop disrespecting our Flag & Country, you will see change take place fast. Fire or suspend!" he tweeted.
A small number of NFL players had been taking a knee during the national anthem to protest racism and police brutality since former 49ers quarterback Colin Kaepernick started the protest in 2016.
Following Trump's comments at the rally and on Twitter, players from almost every NFL team knelt or stood with their arms locked during the national anthem.
