Michael Cohen has asked a California court to make Michael Avenatti leave him alone.
Cohen is the former personal lawyer for U.S. President Donald Trump.
Avenatti represents adult film actress Stormy Daniels, who allegedly had a sexual encounter with Trump.
Cohen asked a federal court Thursday to issue a restraining order against Avenatti.
He wants to keep Avenatti from speaking publicly about a lawsuit he filed on behalf of Daniels.
