According to a statement from UK police, four adults were taken into custody under allegations of malicious communications after an “unauthorised projection” at Windsor Castle, which officials labeled as a “public stunt.” The individuals are still being held.

A birthday card Trump allegedly wrote to Epstein more than 20 years ago — which the White House denies is authentic — was also projected onto the castle, along with pictures of Epstein’s victims, news clips about the case and police reports.

Trump was friends with Epstein before becoming president, but had a falling out with the former financier years before his 2019 death in prison.
