ROBERT MUELLER/RUSSIA/SOCIAL MEDIA/TRUMP PEOPLE: “A social media expert who worked with influential Donald Trump ally Roger Stone during the 2016 U.S. presidential race testified before a federal grand jury on Friday [6-1-18] after being subpoenaed by the special counsel investigating potential collusion between Trump’s campaign and Russia. Jason Sullivan arrived at the federal courthouse in Washington at around 9 a.m. and left the courthouse at around 11:30 a.m. After his closed-door grand jury testimony ended, Sullivan declined to comment on what questions Special Counsel Robert Mueller’s team had asked him. Knut Johnson, one of two lawyers who accompanied Sullivan to the courthouse, said because the testimony was part of an ‘ongoing investigation,’ neither Sullivan nor his lawyers wished to discuss details of it. Johnson said Sullivan was ‘open’ and ‘truthful’ in his statements to the grand jury. Sullivan received two subpoenas last month from Mueller’s office, one summoning him to testify before the Washington grand jury and the second requiring him to provide documents and other data to investigators, according to copies of the subpoenas seen by Reuters.”
