The Department of Justice has notified the House Judiciary Committee that it can expect to receive a written summary of special counsel Robert Mueller's investigative conclusions on Sunday evening, a lawmaker on the panel confirmed to The Hill.

The lawmaker said Congress was prepared to receive the findings by 5 p.m. Other news outlets reported that Barr planned to deliver his summary as soon as 4 p.m.

News of the written briefing comes after Attorney General William Barr notified lawmakers on the House and Senate Judiciary panels Friday evening that he could be ready to brief lawmakers as soon as this weekend on the "principal conclusions" reached by Mueller in his sprawling 22-month probe.

Since the announcement, a high level of intrigue has surrounded what the findings could be, but it also has had Congress and the White House bracing for whatever possible conclusions the report may reveal.

Lawmakers have urged the Department of Justice to quickly make information from the report available to Congress and the public, with some indicating that they will fight to gain access to the underlying evidence that supports Mueller's findings.

The White House said Friday that President Trump, who has been traveling this weekend, has not been briefed on the report's findings.
