George Nader, a Lebanese American businessman who became a major witness in former Special Counsel Robert Mueller’s investigation, was indicted in a Virginia federal court on child pornography charges, the Washington Post reported Monday.

Nader has previously faced related charges.

Most notably, he was present at a mysterious meeting with Blackwater founder and Trump ally Erik Prince in Seychelles, which was also attended by an official tied to the Russian government. It’s not clear exactly what the nature of the meeting was, though many of Prince’s public remarks about the encounter appear to be false. Mueller scrutinized the meeting as a part of his investigation and interviewed Nader about it, but he was unable to satisfactorily answer all outstanding questions about the event.
