Attorney General Barr is likely going to release the "vast majority" of the Mueller report, including showing how it reached its 'no collusion' conclusion and begging the question why was there an investigation "in the first place," according to President Donald Trump's lawyer Rudy Giuliani.

"He is going to release, I'm sure, the vast majority of it," Giuliani told "The Cats Roundtable" on 970 AM-N.Y., The Hill reported.

Special counsel Robert Mueller's 300-plus-hundred-page report was summarized by AG Barr to reveal no evidence of President Trump's campaign conspiring with Russia to meddle in the 2016 presidential election. But that result did not satisfy President Trump's political opponents, who are now calling for the full Mueller report to be released.

While the full Mueller report is guarded by Justice Department privacy protections and regulations, including classified grand jury testimony, Giuliani still expects a "full explanation of Mueller," according to the report.

"I think you're going to get the full explanation of Mueller, I think you're going to see no collusion of any kind, which raises the question why do we have this investigation in the first place?" Giuliani added to host John Catsimatidis, per The Hill.
