Mueller wrote the letter on March 27 just days after Barr issued a four-page memo that summarized what he said were the main conclusions of the Special Counsel's Russia report, the Washington Post reports. Barr had just announced that Trump had been cleared of obstruction of justice and there was no conspiracy between his campaign and Russia to interfere in the election.
