NATIONWIDE — The former Navy SEAL who claims he fired the shots that killed Osama bin Laden is facing a ban from Delta Air Lines after he boasted on Twitter about not wearing a facemask on a flight. 

“I’m not a p****,” Robert O’Neill wrote Wednesday in the now-deleted tweet.

Behind O’Neill in the photo was a man wearing a Marine Corps hat and a facemask. O’Neill later said he was not taking a shot at that man, adding, “I love Marines.”

O’Neill says his wife deleted the tweet, which got the attention of actress Alyssa Milano, who recently revealed she was diagnosed with COVID-19

“You do realize you may be a-symptomatic and give the virus to other people that could potentially kill them. I think that makes you a sociopath,” she said in a tweet.

O’Neill responded to Milano by saying he does wear a mask and that his tweet was an “attempt at a joke (that) did NOT go over well.” He, however, has repeatedly expressed skepticism about the seriousness of the coronavirus, which has killed 173,000 Americans, and previously tweeted on a flight that people who were wearing masks were “sheep.”

“I am not the bad guy. I killed the bad guy,” O’Neill said in a later post.

The U.S. Centers for Disease Control Prevention recommends that to help prevent the spread of the coronavirus people wear masks in public settings when around individuals outside of their household, especially when social distancing cannot be maintained. All U.S. airlines mandate passengers wear masks aboard flights, even insisting they do so from the moment they step inside the airport.

Delta said it is considering banning O’Neill over his tweet.

“We’re aware of this customer’s tweet and are reviewing this event,” a spokesperson told the New York Post. “All customers who don’t comply with our mask-wearing requirement risk losing their ability to fly Delta in the future.”

Delta CEO Ed Bastian told CNN last week the airline had already banned “well over 100 people” for refusing to wear masks.

O’Neill says he shot bin Laden three times, killing the al-Qaida leader during a raid in Pakistan in 2011. But some members of SEAL Team Six have credited another member with firing the fatal shot.
