The Mueller Report:
Fourth, if we had confidence after a thorough investigation of the facts that the President clearly did not commit obstruction, we would so state. Based on the facts and the applicable legal standards, however, we are unable to reach that judgment. The evidence we obtained about the President’s actions and intent presents difficult issues that prevent us from conclusively determining that no criminal conduct occurred. Accordingly, while this report does not conclude that the President committed a crime, it also does not exonerate him.
