Blackwater founder Erik Prince has spoken to investigators on Special Counsel Robert Mueller’s team, the Daily Beast reported Wednesday, citing two unnamed sources familiar with the matter.

A spokesperson for Prince, Marc Cohen, did not confirm or deny the meeting to the publication.

“Erik gave a full and frank public account of events as they concern him to the intelligence committee and he has nothing else to add on this topic,” Cohen said. Prince testified before the House Intelligence Committee in November of last year.

The Daily Beast said it wasn’t clear what Mueller’s team discussed with Prince.

But several outlets have reported in the past on Mueller’s interest in a meeting days before President Donald Trump’s inauguration in the Seychelles between Prince; Kirill Dmitriev, the head of the Russian sovereign investment fund; and, reportedly, George Nader, an adviser to the United Arab Emirates with deep ties in Trump’s circles.

The New York Times reported in March that Mueller’s team had questioned Nader, and Nader has since testified before a grand jury for Mueller’s probe, the Washington Post reported.
