After being invited by the National Football League to place an ad in the Super Bowl LII program, American Veterans (AMVETS), an organization focused on the well-being of US veterans, announced Monday that the league had rejected the advertisement they submitted.

The ad, which shows soldiers saluting the American flag with the words "Please Stand" hovering above, is a pointed response to the movement of NFL players taking a knee during the national anthem to protest racial inequality and injustice.
