Leonardo DiCaprio testifies for prosecution at trial of Fugees rapper Pras Michel

Academy Award winner Leonardo DiCaprio took the stand Monday as the first blockbuster witness in the star-studded trial of former Fugees member Pras Michel, CNN reports.

Michel is accused of participating in a global campaign-finance conspiracy funded by Jho Low, a Malaysian businessman who allegedly stole billions of dollars from a Malaysian sovereign wealth fund, 1MDB. Michel has pleaded not guilty.

DiCaprio, who reportedly testified to the grand jury that handed up Michel’s indictment, is not accused of any wrongdoing.

Though both Michel and Low are both facing charges in the US, Low remains at large so Michel is on trial alone.

DiCaprio testified for about an hour on his relationship with Low in a bid by prosecutors to show that Low used stolen money to curry favor with actors, models and politicians in the United States. It’s likely that prosecutors are using DiCaprio as a charismatic figure to both explain the extent of the alleged Malaysian money scheme, and also to bring star power that would outshine even Michel.
