Eric Trump, the son of Republican presidential nominee Donald Trump, has been reported to the state Board of Elections by an anti-Trump PAC for posting on Twitter a photo of his ballot with Trump’s bubble filled in.

Democratic Coalition Against Trump, an arm of the Keep America Great PAC, announced Tuesday afternoon that it had filed a complaint with the state Board of Elections’ enforcement counsel after he tweeted out a photo of his partially completed ballot. The tweet was deleted, though not before the anti-Trump group snagged a screenshot.

The Trump campaign did not immediately comment.

It is illegal in New York for voters to show their completed ballots to anyone. That section of state election law was bolstered last week by a federal judge’s decision not to issue an injunction that would have allowed voters to tout their votes through photos posted on social media, even as “ballot selfies” have become a hot way to show political pride nationwide.

It is not illegal to take photographs inside a polling place or voting booth or that depict a blank ballot. However, polling site workers do reserve the right to prohibit photography they deem to be disruptive.

To be sure, Eric Trump most certainly was not the only New Yorker to post a photo of a completed ballot on social media Tuesday.
