WASHINGTON (Reuters / August 3, 2017) - Grand jury subpoenas have been issued in connection with a June 2016 meeting that included President Donald Trump's son, his son-in-law and a Russian lawyer, two sources familiar with the matter told Reuters on Thursday.
The sources added that special counsel Robert Mueller had convened a grand jury in Washington to investigate allegations of Russian meddling in the 2016 U.S. election.
Russia has loomed large over the first six months of the Trump presidency, with U.S. congressional panels also investigating the Russian election interference that U.S. intelligence agencies believe was meant to tilt the vote in Trump's favor.
Mueller's use of a grand jury could give him expansive tools to pursue evidence, including issuing subpoenas and compelling witnesses to testify. The impaneling of the grand jury was first reported by the Wall Street Journal.
