Comedienne Kathy Griffin joined the attack on the Covington Catholic school kids on Tuesday, with a tweet accusing them of displaying a “Nazi sign.”

The standup, whose career went on the skids after she publicized a photo shoot where she was seen holding up the bloody, severed head of President Donald Trump. Posted a tweet on Tuesday featuring a photo of some Covington High School basketball players with a caption saying, “Covington’s finest throwing up the new nazi sign.”

In the pic, one of the players is making a sign for the number three, with the thumb and forefinger together.

Griffin deleted the tweet a short time later. But some saved screen shots of the attack.

The claim quickly fell apart on the bellicose comedienne when people began replying to her tweet with images of black NBA players holding their hands in the exact same way the Covington players had. Because, that particular sign is the hand signal for a made 3-point shot. Not, the symbol of white racism.

Both conservatives and liberals posted images showing Griffin that her accusation had no basis in truth.

Washington Examiner writer Siraj Hashmi, for instance saved several replies to Griffin noting that the tweets were a “bipartisan dunking on Kathy Griffin, a tradition unlike any other.”

Indeed, as Leftist MSNBC host Chris Hayes noted in his reply, the hand signal “almost certainly” meant that a player had achieved a three-point shot.

There are any number of photos showing players — especially in basketball — celebrating by displaying the three-point-shot hand signal.

Look, I have no idea what racist tones you’re ascribing to the “ok” hand signal, but in basketball country, it’s in reference to a three point shot. pic.twitter.com/OmSlAZp6rd — Gwenny (@gwendolynclare) January 22, 2019

Get a grip. It’s the signal for a three point shot. pic.twitter.com/gKFPh2EHIG — DashingYoungMilkman (@myfriendmikey) January 22, 2019
