Donald Trump went to a "Heroes and Villains"-themed costume party on Long Island last night, which is enough of a joke in and of itself. But it gets better—instead of donning a costume, the President-elect dressed as himself.

Trump's chief strategist and alleged white nationalist Steve Bannon also attended the party and reportedly didn't wear a costume.

The party was held at a mansion on Long Island's North Shore belonging to Trump transition team member Rebekah Mercer.

Mercer, a hedge fund heiress who Politico recently called the "most powerful woman in GOP politics," ran a pro-Trump super PAC called Make America Number 1 and has reportedly donated more than $30 million to 30 conservative nonprofits.

The Campaign Legal Center, a non-profit election law watchdog organization, has accused the Mercer family of illegally paying Steve Bannon through their PAC while he was working as Trump's campaign CEO. After Bannon left Breitbart to join the Trump campaign in August, the Mercer-backed PAC paid nearly $280,000 to Glittering Steel LLC, a production company which has been described as a front for Bannon. During that same period, the Trump campaign didn't report making any payments to Bannon. Campaign finance laws prohibit super PACs from communicating with or contributing to campaigns or parties.

A pool reporter asked Trump if his (lack of a) costume meant he was attending as a hero or a villain. According to NBC, Trump's campaign manager Kellyanne Conway emerged from a car dressed as Supergirl and answered the reporter's question: "A hero, all the way!"

America is a cruel, sick joke.
