This year marked the 19-year anniversary of the horrific 9/11 attacks that left about 3,000 Americans dead.

Despite this tragic anniversary, millionaire NBA basketball players decided to disrespect ever single life that was lost on 9/11 as they knelt for the National Anthem.

Many Twitter users spoke out against the NBA after the sickening stunt

“Rough look for NBA players to kneel for the national anthem on the anniversary of 9/11,” tweeted sports reporter Clay Travis.

“NBA players kneeled during the national anthem on the anniversary of 9/11,” tweeted David Hookstead. “They couldn’t even stand to honor the heroes who sacrificed and died. It’s disgusting.”
