The White House immediately declared victory as well.
“The Special Counsel did not find any collusion and did not find any obstruction,” said Press Secretary Sarah Huckabee Sanders in a statement.
“Attorney General Barr and Deputy Attorney General Rosenstein further determined there was no obstruction. The findings of the Department of Justice are a total and complete exoneration of the President of the United States,” Sanders told reporters.
While the letter was immediately hailed by Republicans as the end of the investigation, it also left Democrats with some tantalizing tidbits which they are sure to pursue on the obstruction issue, specifically one line cited by the Attorney General in his Sunday letter to the Congress.
"The Special Counsel states that 'while this report does not conclude that the President committed a crime, it also does not exonerate him,'" the Attorney General wrote, in quoting the Mueller report’s section about the issue of obstruction of justice.
"Special Counsel Mueller clearly and explicitly is not exonerating the President, and we must hear from AG Barr about his decision making and see all the underlying evidence for the American people to know all the facts," said Rep. Jerry Nadler (D-NY), the Chairman of the House Judiciary Committee.
Other Democrats also made clear they want more than just the four page summary written by the Attorney General, as Nadler vowed to bring Attorney General Barr in for hearings.

As for the possibility of the Mueller report being made public, Barr told Congress in his letter that he would still try to err on the side of transparency.
“I am mindful of the public interest in this matter. For that reason, my goal and intent is to release as much of the Special Counsel's report as I can consistent with applicable law, regulations, and Departmental policies,” Barr wrote.
