US congressional leaders are awaiting conclusions from Special Counsel Robert Mueller's report into alleged collusion between the Trump campaign and Russia, with early findings expected Sunday.
The long-awaited report was submitted on Friday to Attorney General William Barr, who spent Saturday at the justice department poring over the document.
The report is the culmination of two years of investigation by Mr Mueller.
A justice department official said it did not call for new charges.
In the course of their investigation, Mr Mueller and his team have already charged 34 people - including six former Trump aides and a dozen Russians - as well as three companies.
