Mueller Delivers Report on Trump-Russia Investigation to Attorney General

The special counsel, Robert S. Mueller III, has delivered a report on his inquiry into Russian interference in the 2016 election to Attorney General William P. Barr, according to the Justice Department, bringing to a close an investigation that has consumed the nation and cast a shadow over President Trump for nearly two years.

Mr. Barr told congressional leaders in a letter late Friday that he may brief them within days on the special counsel’s findings. “I may be in a position to advise you of the special counsel’s principal conclusions as soon as this weekend,” he wrote in a letter to the leadership of the House and Senate Judiciary committees.

It is up to Mr. Barr how much of the report to share with Congress and, by extension, the American public. The House voted unanimously in March on a nonbinding resolution to make public the report’s findings, an indication of the deep support within both parties to air whatever evidence prosecutors uncovered.

Mr. Barr wrote that he “remained committed to as much transparency as possible and I will keep you informed as to the status of my review.” He also said that Justice Department officials never had to check Mr. Mueller because he proposed an inappropriate or unwarranted investigative step — an action that Mr. Barr would have been required to report to Congress under the regulations. His statement suggests that Mr. Mueller’s inquiry proceeded without political interference.
