Celebrity lawyer Michael Avenattii has been arrested on charges related to an alleged $20 million extortion of the athletic apparel company Nike, federal authorities said Monday.

A press conference is scheduled to discuss the charges against Avenatti in Los Angeles on Monday afternoon.

Avenatti had represented porn star Stormy Daniels in her lawsuit against President Donald Trump and his former lawyer Michael Cohen.

The charges were revealed less than an hour after Avenatti announced a press conference to discuss claims against Nike.
