New York Rep. Lee Zeldin is again taking on professional football players who protest during the National Anthem, telling them to “stand up and show some respect.”

The Republican, who served in the U.S. Army, posted an image of former San Francisco 49ers players Colin Kaepernick and Eric Reid kneeling while showing soldiers holding them up.

“On the shoulders, blood, service, and sacrifice of true giants,” he said. “Stand up and show some respect for your right to live in the greatest nation on earth and make a fortune playing a football game.”

President Donald Trump continued his attacks on NFL players protesting racial injustice after the first round of NFL pre-season games last week in which several players took a knee or raised a fist in protest during the anthem. And this is not the first time Zeldin commented on NFL players kneeling, which Kapernick began doing in 2016 to protest police violence against African-Americans.
