Members of Robert Mueller's team reportedly feel that Barr did not adequately represent the key findings of their two-year investigation into Russian election interference and possible collusion with Donald Trump's campaign.
On "America's Newsroom" Thursday, Starr, a former independent counsel whose investigation into Whitewater led to then-President Bill Clinton's impeachment hearings, said information that could compromise national security or grand jury secrecy must be redacted from the report. Barr and Deputy Attorney General Rod Rosenstein, instead, made the decision, saying that the evidence was "not sufficient to establish that the president committed an obstruction-of-justice offense".
The House Judiciary Committee on Wednesday voted along party lines to subpoena the full report.
"Despite his history of support for making the Mueller report public, Trump predicted nothing would make Democrats content, citing years of wasted efforts to bring him down on collusion and obstruction charges". The authorization does not issue subpoenas, but gives the panel the option to do so should they feel it necessary. "We have a right to see the information in the Mueller report".
Attorney General William Barr has pledged to release a redacted version of the report by mid-April.
In another development, the Wall Street Journal reported that the Democratic-led House Intelligence Committee, led by Trump critic Adam Schiff, is seeking an interview with and documents from a top organiser on Trump's inaugural committee.
But House Democrats are moving to subpoena a full, unredacted copy of the report from the Justice Department.More news: Replacing Obamacare is still a Republican duty
The vote also gives Nadler the discretion, Politico added, "to issue a subpoena at any time to Attorney General William Barr, a move that likely would launch a legal confrontation between Congress and the Justice Department".
The Post also reveals new details about the layout of the report, which was prepared "so that the front matter from each section could have been released immediately - or very quickly", according to an official briefed on the matter.
Mr Mueller spent almost two years investigating allegations of Russian meddling to help Mr Trump defeat his Democratic opponent Hillary Clinton. "R. Crim. P. 6 (e)", which protects grand jury information.
During an appearance Thursday morning on Fox News's "Fox & Friends", White House spokeswoman Sarah Sanders pointed to Trump's remarks Wednesday when asked whether Trump intends to let his returns become public.
"I think Mueller had really no choice but to punt on this question and leave it to Barr to decide, and Barr, predictably, concluded there was no basis for a prosecution", Lazare told hosts John Kiriakou and Walter Smolarek.
Angel Padilla, Indivisible's national policy director, argued that both Barr and the Trump administration "have drawn unverifiable conclusions from a report no one else has been allowed to see while ignoring the overwhelming majority of Americans who want it to be made public".
