Depp is suing Heard for defamation over an essay she wrote for The Washington Post in 2018, in which she said she had become the "public figure representing domestic abuse." Although the article never mentions Depp by name, his attorneys said it indirectly refers to allegations she made against him during their 2016 divorce.

The trial in Fairfax County, Virginia, is expected to take weeks.
