As a candidate, Donald Trump vowed to personally respond to veterans’ complaints if he won the election. But now the president appears to have blocked a veterans group that has been critical of him on Twitter., a veterans-run political watchdog group that bills itself as “the largest progressive organization of veterans in America,” tweeted a screenshot on Tuesday that appeared to show that Trump had blocked the group on Twitter.

“The Commander in Chief can block @VoteVets, the voice of 500k military veterans and families, but we will NOT be silenced,” VoteVets wrote.

The tweet quickly went viral and was retweeted or commented on by former first daughter Chelsea Clinton, CNN’s Jake Tapper and Saturday Night Live alum Ana Gasteyer.

VoteVets hasn’t shied away from publicly criticizing Trump, blasting the president on Twitter for his proposed ban on travelers from six Muslim-majority countries from entering the U.S., for allegedly violating the Constitution’s Emoluments Clause, and for his praise of Russian President Vladimir Putin.

Other veterans on Twitter have said that Trump blocked them too.

But the alleged blocks have not been limited to veterans. Author Stephen King, who has frequently spoken out against the president and his administration on Twitter, tweeted Tuesday that he was also blocked.

King and others questioned whether the blocking spree could be a hoax. When asked if the blocks were legitimate or potentially a hoax or technical glitch, a Twitter spokesman told PEOPLE in a statement: “Unfortunately, we don’t comment on that type of information for any accounts.”

The White House did not immediately respond to requests for comment.

One very vocal Trump critic who wasn’t blocked? Harry Potter author J.K. Rowling, who offered to help King stay informed.

“I still have access,” she said of Trump’s tweets. “I’ll DM them to you.”
