Barr was on pace to release his first summary of Mueller’s findings on Sunday, people familiar with the process said.

The attorney general’s decision on what to finally disclose seems almost certain to set off a fight with congressional Democrats, who want access to all of Mueller’s findings – and supporting evidence – on whether Trump’s 2016 campaign coordinated with Russia to sway the election and whether the president later sought to obstruct the investigation.

Barr and Deputy Attorney General Rod Rosenstein, who appointed Mueller and oversaw much of his work, analyzed the report on Saturday, laboring to condense it into a summary letter of main conclusions. Mueller delivered his full report to Barr on Friday.
