Robert Mueller's spokesman on Tuesday strongly denied claims in a new Michael Wolff book that the special counsel prepared a draft indictment of President Donald Trump on obstruction of justice. "The documents described do not exist," Mueller spokesman Peter Carr said, referring to the purported three-count charging document against Trump by the special counsel as reportedly described in Wolff's forthcoming book, "Siege: Trump Under Fire." It was an unusually blunt and direct response from Carr, who routinely declined to comment during the secretive 20-month investigation.
