"the report explained:
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."
Aides refused to help efforts to obstruct
Mueller reports that because aides and advisers to Trump refused to "carry out orders," the President was prevented from influencing the special counsel's investigation.
Here's the relevant line: "The President's efforts to influence the investigation were mostly unsuccessful, but that is largely because the persons who surrounded the President declined to carry out orders or accede to his requests."
Mueller says Congress can pursue investigation of Trump obstruction
Members of Congress will zero in on one critical section in Mueller's report. The special counsel provides a constitutional justification for its own investigation, but also points out that Congress can also apply obstruction laws in investigating and impeaching a sitting president.
Here's the relevant line in the report: "The conclusion that Congress may apply the obstruction laws to the President's corrupt exercise of the powers of office accords with our constitutional system of checks and balances and the principle that no person is above the law."
The report also cites Supreme Court precedent and the separation of powers to say "the Constitution does not categorically and permanently immunize a President for obstructing justice."
"Bad Mueller Report! Down, Boy!"
