Clinton family ally Sidney Blumenthal said a new book telling of a “deep state” plot to undermine President Trump contained “factual errors” about him and that he asked the publisher to correct them.

An Oct. 25 Fox News report cited a source who said Blumenthal sent “threatening letters” to investigative journalist Lee Smith and his publisher Center Street, a division of Hachette Book Group, in an effort to stop the publication of Smith’s book because he viewed it as defamatory.
