The Mueller team is asking for more witness testimony, signaling that Mueller and the Justice Department may be considering an additional indictment of Roger Stone or have plans to charge others, CNN reports. A defense attorney for Andrew Miller, a former employee of Stone’s, who’s fighting a subpoena from Robert Mueller’s investigation into Russian interference in the 2016 election, learned Monday afternoon that the special counsel still wants witness testimony for a federal grand jury, according to the report. Mueller is seeking information Miller has about Stone’s communications regarding Wikileaks and Russian hackers around the time they published hacked Democratic emails. Paul Kamenar, Miller’s defense attorney, says the assertion from Mueller’s team made clear to him that they are considering additional indictments. The development comes after acting Attorney General Matthew Whitaker said that Mueller’s investigation was “close to being completed.”
