With Mueller report in, nothing's over. But for Trump, everything has changed

Special counsel Robert Mueller, whose investigation in large part has defined the first half of President Trump's tenure, was spied in front of the White House on Sunday morning as he and his wife walked across Lafayette Square toward St. John's Episcopal Church.

The former FBI director looked, finally, relaxed.

That wasn't exactly the impact his long-awaited and confidential report had on the rest of official Washington. On a balmy spring Sunday, as Attorney General William Barr delivered the "principal conclusions" of the report to Congress, Republicans declared the president vindicated, and some Democrats found themselves on the defensive.

To be clear, only a summary of Mueller's report, and none of his inquiry's underlying evidence, was released. What's more, federal and state investigations into the president's business organization, his charitable foundation, his payment of hush money during the campaign and his inaugural committee are continuing and could lead to legal troubles down the road.

Even so, Mueller's report, nearly two years in the making, shifted the political landscape.

"The investigation did not establish that members of the Trump Campaign conspired or coordinated with the Russian government in its election interference activities," Mueller's report concluded, according to Barr. But the special counsel said he couldn't reach a conclusion on the question of obstruction of justice: "While this report does not conclude that the President committed a crime, it also does not exonerate him."

Mueller referred that issue to the attorney general. After consulting with other Justice Department officials, Barr said he concluded that the special counsel's investigation wasn't sufficient "to establish that the President committed an obstruction-of-justice offense."
