A protester disrupted the national anthem during the Dallas Cowboys’ game on Sunday by shouting “Vote Republican” and “Stop Abortion.”

The unidentified man walked up and down the roof of the stadium’s field suites as fans stood with their hands over their hearts, according to photo and video taken of the disruption.

He carried a sign reading “Stop Abortion” on one side, and “Vote Republican” on the other, according to video from NBC 5 Sports in Dallas.

Video from the game shows the man being escorted back to the stands by security, and he was reportedly not asked to leave the stadium.

The incident occurred ahead of the Cowboys’ 40-7 win against the Jacksonville Jaguars.

A number of NFL players have come under fire, largely from conservatives, for kneeling during the anthem to protest racial inequality and police brutality.

Dallas Cowboys owner Jerry Jones took a hard line on the protests, which have stretched into the current season, saying earlier this year that his players would be required to stand during the anthem.
