Special Counsel Robert Mueller's investigation into Russian interference in the 2016 presidential election has found that the Donald Trump campaign did not conspire or coordinate with Russia in its efforts to influence the 2016 U.S. presidential election, according to Attorney General William Barr's summary of the report released on March 24.

"The Special Counsel's investigation did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 U.S. presidential election. As the report states: '[T]he investigation did not establish that members of the Trump Campaign conspired or coordinated with the Russian government in its election interference activities.'," the summary stated. The summary letter to leaders of the Committee of the Judiciary for both the Senate and the House of Representatives was published on The New York Times' website.

Barr wrote that the Mueller report, which concludes a two-year saga during which Mueller's team has brought dozens of charges, could not conclusively determine whether Trump obstructed justice. Mueller's report cited evidence on both sides of the question, according to his summary. Barr said he and Deputy Attorney General Rod Rosenstein ultimately determined that there was insufficient evidence to establish that Trump committed obstruction of justice.

"After reviewing the Special Counsel's final report on these issues; consulting with Department officials, including the Office of Legal Counsel; and applying the principles of federal prosecution that guide our charging decisions, Deputy Attorney General Rod Rosenstein and I have concluded that the evidence developed during the Special Counsel's investigation is not sufficient to establish that the President committed an obstruction-of-justice offense," Barr wrote in his summary. "Our determination was made without regard to, and is not based on, the constitutional considerations that surround the indictment and criminal prosecution of a sitting president."

The Mueller report does not recommend any further indictments, according to the summary.

Around the same time the summary was made public, Trump tweeted: "No Collusion, No Obstruction, Complete and Total EXONERATION, KEEP AMERICA GREAT!"

Some of President Trump's closest associates — including his former campaign chairman Paul Manafort, and former personal attorney Michael Cohen — have already pleaded guilty to charges stemming from investigations related to the Mueller probe.
