REP. JOSE SERRANO (D-NY): With regard to your March 24th and 29th letters to the judiciary committees, did special counsel Mueller or anyone on his team have a role in drafting them or reviewing them in advance to use any of the summary documents prepared by the special counsel in drafting these documents? ATTORNEY GENERAL WILLIAM BARR: The letter of the 24th, Mr. Mueller’s team did not play a role in drafting that document, although we offered him the opportunity to review it before we sent it out and he declined that. The letter on the 29th, I don’t believe that was reviewed by Mr. Mueller or that he participated in drafting that letter.

In a March 24th letter sent to the House and Senate Judiciary Committees, the Department of Justice said the special counsel did not find evidence that President Donald Trump’s presidential campaign “conspired or coordinated” with the Russian government during the 2016 presidential election. Further, Mueller did not “exonerate” the president of obstructing justice, according to Barr, who stated that the report “sets out evidence on both sides of the question.”
