PHILADELPHIA—The United States Military Academy, also known as West Point, is investigating a hand gesture made by several cadets and midshipmen during an ESPN pre-game broadcast at the army-navy game Saturday after clips of the signal went viral because of its possible association with white supremacy.

“West Point is looking into the matter,” a spokesperson said in an emailed statement. “At this time we do not know the intent of the cadets.”

The U.S. navy did not return a request for comment about a similar gesture used by its midshipman.

During the broadcast at Lincoln Financial Field in South Philly, at least three or four students are seen flashing an upside-down “OK” sign with their hands behind ESPN reporter Rece Davis.

Many on social media expressed shock and outrage because of the symbol’s recent association with white power. Others argued that the students were just playing a game.

According to a 2017 article from the Anti-Defamation League, use of the symbol began on the website 4chan as a “hoax campaign” to troll liberals. But this year, the ADL added the gesture to its hate symbols database, noting that while it began as a hoax, it has started “being used in some circles as a sincere expression of white supremacy.”

However, some on Twitter suggested the gestures were just part of something called the circle game, wherein someone makes a circle gesture with their fingers and if another person looks at it, the instigator gets to punch them.

Even if the gesture does have multiple meanings, it’s been taken very seriously as of late. This year, a Chicago Cubs fan was banned from Wrigley Field for making the gesture during a television broadcast and a staffer at Universal Studios was fired for making the gesture while posing for a photo with a child.

Some suggested that whatever the students’ motive, their actions showed poor judgment.
