2016 ELECTION/ROBERT MUELLER/RUSSIA INVESTIGATION/TRUMP AS PRESIDENT: “U.S. Attorney General William Barr’s conclusion that President Donald Trump did not obstruct justice, revealed publicly on Sunday in a letter to lawmakers, reflects inherent difficulties in proving such an obstruction case, legal experts said. Barr sent a four-page letter to congressional leaders summarizing a report by U.S. Special Counsel Robert Mueller handed in on Friday 3-22-19] , which remains confidential. Mueller was appointed to investigate whether Trump’s campaign conspired with Russia to influence the 2016 election and to probe whether the president later unlawfully sought to obstruct the probe. Mueller vindicated Trump on the core question of Russian collusion, writing in his report that ‘the investigation did not establish that members of the Trump campaign conspired or coordinated with the Russian government in its election interference activities,’ according to Barr’s letter. While Mueller stopped short of determining whether Trump obstructed justice, Barr concluded there was insufficient evidence to bring such a case.”
