Special counsel Robert Mueller did not make the decision himself on whether to prosecute President Trump on obstruction, the attorney general wrote. Instead, Mueller left it up to Attorney General William Barr and Deputy Attorney General Rod Rosenstein.

Barr and Rosenstein did not find they could bring a criminal case with proof beyond a reasonable doubt that Trump’s actions obstructed a specific proceeding.

Barr notes the “absence of such evidence” related to crimes around the Russian election interference, weighed on his decision regarding obstruction.

Barr explains in the letter that Mueller’s investigation into obstruction of justice found the President’s actions were not “done with corrupt intent.”
