ROUGH CUT (NO REPORTER NARRATION) Attorney General William Barr arrived for the work at the Department of Justice on Thursday ahead of his planned release of the Mueller report.
Barr's planned release of the nearly 400-page report comes after Mueller wrapped up his 22-month investigation last month into the Trump campaign's contacts with Russia and questions about obstruction of justice by the president.
Its disclosure, with portions expected to be blacked out by Barr to protect some sensitive information, is certain to launch a new political fight spilling into the halls of Congress and the 2020 presidential campaign trail, as Trump seeks re-election in a deeply divided country.
The release marks a watershed moment in Trump's presidency, promising new details about some of the biggest questions in the probe, including the extent and nature of his campaign's contacts with Russia and actions Trump may have taken to hinder the inquiry including his 2017 firing of FBI Director James Comey.
It also may deepen an already bitter partisan rift between Trump's fellow Republicans, most of whom have rallied around the president, and his Democratic critics, who will have to decide how hard to go after Trump as they prepare congressional investigations of his administration.
Barr said he would hold a news conference at 9:30 a.m.
(1330 GMT) on Thursday to discuss the report, along with Deputy Attorney General Rod Rosenstein, who appointed Mueller as special counsel in May 2017.
