Lawyers for Hunter Biden plan to sue Fox News “imminently” on defamation grounds, according to a letter sent to the network.

The Tuesday letter, obtained by NBC News, which served as a litigation notice for Fox News, alleges its “conspiracy and subsequent actions to defame Mr. Biden and paint him in a false light, the unlicensed commercial exploitation of his image, name, and likeness, and the unlawful publication of hacked intimate images of him.”
