The FBI has opened an investigation into Harvey Weinstein, DailyMail.com has exclusively learned.

DailyMail.com understands the move came at the behest of the Department of Justice, run by Donald Trump's Attorney General Jeff Sessions, which instructed the bureau to investigate the mounting allegations leveled at the movie mogul.

While it is unknown whether the DOJ order came directly from Sessions, the move is likely to be seen in a political light given Weinstein's friendship with Trump foe Hillary Clinton.

The move by the DOJ came amid rumors that Weinstein was planning on heading to Europe for sex rehab – leading to fears of a Roman Polanski-style situation where he dodges prosecution in the U.S.

However the movie exec appeared to have a last minute change of heart and decided to travel to Arizona for treatment instead at The Meadows center.
