Robert Mueller, the special counsel tasked with investigating potential coordination between Donald Trump's presidential campaign and Russia, has issued grand jury subpoenas recently, NBC News reported on Friday. He is reportedly seeking testimony from public relations executives who worked on a 2012-2014 lobbying campaign organized by former Trump campaign chairman Paul Manafort. This report marks the first public indication that Mueller is starting to compel witness testimony before a grand jury. Manafort has been a key figure in the larger probe and his Virginia apartment was raided by FBI agents last month.
