Johnny Depp took the stand on Tuesday and began his testimony by explaining why he’s suing Amber Heard for defamation.

Actor Johnny Depp is suing ex-wife Amber Heard for $50 million for defamation in connection with Heard’s 2018 Washington Post op-ed. Heard’s article did not specifically name Depp. Amber Heard is counter-suing Depp for $100 million.
