Mueller examined multiple episodes for possible obstruction. Investigators examined about 10 episodes in which the president may have obstructed justice, but Mr. Mueller said he could not reach a conclusion. Accordingly, while this report does not conclude that the president committed a crime, it also does not exonerate him.”Mr. Barr, however, opted to reach the conclusion that Mr. Mueller would not. Among the incidents that the special counsel examined was Mr. Trump’s decision to fire James B. Comey, the F.B.I. director, in May 2017, and an attempt by the president a month later to have his White House counsel, Donald F. McGahn II, fire Mr. Mueller.
