"The findings of the Department of Justice are a total and complete exoneration of the President of the United States," White House spokeswoman Sarah Sanders said. Trump tweeted "total EXONERATION" shortly after the summary was released, despite Barr's letter saying the report does not exonerate him on obstruction. The report found no evidence President Donald Trump colluded with Russia.

He also said of Russia's hacking operation in 2016, "The Special Counsel did not find that the Trump campaign, or anyone associated with it, conspired or coordinated with the Russian government in these efforts, despite multiple offers from Russian-affiliated individuals to assist the Trump campaign." Speaking to reporters before he departed Florida to return to the White House, Trump called the Mueller probe "an illegal takedown that failed". "It's a shame that our country had to go through this and a shame the president had to go through this," he said. Loading It's sure to be only the beginning of months of fighting in Congress - and perhaps in the courts - over how much should be disclosed from Mueller's report. Barr said in a letter to Congress on Friday that after this initial summary he'll consult with Mueller and Deputy Attorney Rod Rosenstein "to determine what other information from the report can be released to Congress and the public".

Nothing in the Justice Department's regulations on special counsels would prevent Barr from releasing Mueller's report once certain material is redacted, including classified matters and information about continuing law enforcement operations. But Barr has cited the department's policies against publicly criticising someone who isn't indicted - and against indicting a sitting president. Democratic lawmakers already have demanded the full report as well as the underlying evidence so they can pursue their own investigations. The Democratic candidates who seek to replace him in 2020 joined in demanding the full release of the report. Justice Department officials, who described Mueller's report as comprehensive, said he didn't recommend any additional indictments and doesn't have any secret indictments under seal.

Before completing his probe, Mueller helped secure guilty pleas from five people involved in Trump's presidential campaign - including his campaign chairman Paul Manafort and Michael Flynn, who became his first national security adviser - though none admitted to conspiring with Russian operatives. He also indicted more than two dozen Russian hackers and military intelligence officers. While Mueller didn't seek an indictment of Trump or members of his family, they're not necessarily in the clear. Loading Trump faces continuing risk from other investigations, with federal prosecutors in New York looking into his company, presidential campaign and inaugural committee. Mueller has been sharing some matters and handing off others to US attorney's offices in Manhattan; Alexandria, Virginia; and Washington, as well as the Justice Department's national security division. That may keep alive cases that touch on his personal and business affairs. Through a series of indictments, Mueller laid out a picture of operatives and hackers tied to Russian intelligence agencies doing all they could to help put Trump in the White House even as other Russian officials had scores of contacts with people tied to Trump's campaign.

In the letter on Friday to leaders of the House and Senate Judiciary Committees, Barr said, "I remain committed to as much transparency as possible, and I will keep you informed as to the status of my review". But Barr suggested during his confirmation hearing in February that he might exclude any criticism of Trump and others who weren't charged with crimes from the information he'd share with Congress. "If you're not going to indict someone, then you don't stand up there and unload negative information about the person," he said. In addition, Trump and his lawyers have indicated that before any details from Mueller's findings are made public they want to see anything that would disclose the president's private communications. They say they want to preserve their right to assert executive privilege, the doctrine that a president must have the ability to receive candid advice. Congressional Democrats - who now control the House - say they want broad disclosure of Mueller's investigative work, citing the earlier success of Republicans in pressuring the Justice Department to release details they said showed anti-Trump bias in the FBI. They have talked of issuing subpoenas to force disclosure and even public testimony by Mueller.

"It is imperative for Mr. Barr to make the full report public and provide its underlying documentation and findings to Congress," House Speaker Nancy Pelosi and Senate Democratic leader Chuck Schumer said on Friday in a joint statement.

Credit:AP Mueller, a former FBI director, was appointed in May 2017 to conduct one of the most consequential investigations in US history. He hasn't spoken a word in public since then, leaving it to the indictments he's filed to build his case. Beyond Russia's election meddling - which US intelligence agencies found was aimed at hurting Democrat Hillary Clinton and ultimately at helping Trump win - Mueller investigated possible collusion in the operation and whether Trump sought to obstruct justice in what the president has regularly denounced as a "witch hunt".
