Attorney General William Barr had told lawmakers on the Judiciary panels in the House and Senate on Friday evening that he might be able to brief lawmakers as soon as this weekend on the “principal conclusions” reached by Mueller in his sprawling 22-month probe.

Democrats and the administration are poised for a potential showdown over the contents of Mueller's report on his probe into Russian efforts to meddle in the 2016 presidential election, which ended without any new indictments announced by the Justice Department on Friday.

Lawmakers have urged the Justice Department to quickly release to Congress and the public as much information as possible from the report, including underlying evidence supporting Mueller's investigative findings. Mueller on Friday released a confidential copy of his report to Barr, which was being reviewed at the Justice Department on Saturday.

The White House had said Friday that Trump, who was already in Palm Beach, Fla., traveling for the weekend when the report was released, had not been briefed on its findings. White House press secretary Sarah Huckabee Sanders said, “The next steps are up to Attorney General Barr, and we look forward to the process taking its course.”
