Current law states that the Mueller Report must be turned over to the attorney general, in this case the Trump-appointed AG, William Barr. Author Michael Wolff said former Trump advisor Steve Bannon told him that Weissmann was like "the LeBron James of money laundering investigations". Trump has denied collusion and obstruction.
Democrats are anxious that Barr's strict defense of his own prerogative, combined with his stated respect for Justice Department rules advising against both the indictment of a sitting president or impugning an unindicted individual in an investigative report, means potential information implicating President Donald Trump in alleged wrongdoing could be buried.
"This report must see the light of day, must be available to the American public for a catharsis that will allow us to start with the facts, understand what happened and begin to rebuild the faith of the American people", Rep. Jim Himes (D-CT) said, as The New York Times reports.
Several Republicans have also agreed that Mueller should release not simply the full report, but any and all investigative materials that informed it. Bipartisan Senate legislation calling for the report to be made public has stalled. Senate Majority Leader Mitch McConnell's office had no comment.More news: Teenage climate activist nominated for Nobel Peace Prize
The resolution was passed unanimously in a 420-0 vote Thursday.
Despite the House's vote on Thursday, the decision of how much of Mueller's report becomes public still rests in Barr's hands. Four members of Congress voted present - Republicans Justin Amash of Michigan, Matt Gaetz of Florida, Paul Gosar of Arizona and Thomas Massie of Kentucky.
"This resolution is critical because of the many questions and criticisms of the investigation raised by the president and his administration", said House Judiciary Committee Chairman Jerrold Nadler.
If a full report isn't released, House Democrats have made it clear they will do whatever they can to get hold of it. Nadler has said he would subpoena the final report and invite - or even subpoena - Mueller to talk about it. "It is important that Congress stand up for the principle of full transparency".More news: Facebook's massive outage was the result of a server configuration change
Graham said he agrees "with the concept of transparency", but stopped short of supporting Grassley's bill, saying he disagrees with taking discretion away from the attorney general.
Barr, a Trump nominee who took over the Justice Department last month, replaced Jeff Sessions, who the president ousted in November after long complaining that the former senator had recused himself in 2017 from overseeing the Russian Federation probe.
The Mueller investigation so far has resulted in indictments against 34 individuals and three companies, seven guilty pleas and one conviction following a jury trial.More news: AOC accuses Wells Fargo CEO of financing 'caging' of children at border
