The special counsel, Robert Mueller, has submitted his full report on President Trump and Russian interference in the 2016 election to Attorney General William Barr, who now must decide how much of it to release. Barr told congressional leaders Friday that he might 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. The delivery of the report brings an apparent close to an investigation that has consumed the U.S. and cast a shadow over @realdonaldtrump for nearly 2 years. This is a developing story.
