NEW YORK (Reuters) - Grand jury subpoenas have been issued in connection with the June 2016 meeting between Donald Trump Jr., a Russian lawyer and others, two sources familiar with the matter told Reuters on Thursday.
The sources also said special counsel Robert Mueller had convened a grand jury in Washington to investigate allegations of Russias interference in the 2016 elections.
