Hunter Biden declares war on Fox News with threat of "imminent" lawsuit

Hunter Biden is threatening to sue Fox News for defamation, exploitation of his image and publication of hacked photographs, according to a letter obtained by Axios that was sent to the news channel last week.

Why it matters: It's the latest salvo in the president's son's more aggressive legal and press strategy over the past year amid criminal charges and tabloid coverage, and first big move after navigating the impeachment inquiry into his father.

Driving the news: Hunter Biden's legal team wrote that they anticipate "imminent" litigation against Fox News and requested that prominent Fox News hosts, including Sean Hannity, Jesse Watters and Maria Bartiromo, preserve documentation.
