The following is the text of the letter United States Attorney General William Barr sent to Congress on Sunday summarising a report by Special Counsel Robert Mueller on his investigation into Russia's role in the 2016 presidential election:

Dear Chairman Graham, Chairman Nadler, Ranking Member Feinstein, and Ranking Member Collins:

As a supplement to the notification provided on Friday, march 22, 2019, I am writing today to advise you of the principal conclusions reached by Special Counsel Robert Mueller III and to inform you about the status of my initial review of the report he has prepared.

The Special Counsel's Report

On Friday, the Special Counsel submitted to me a "confidential report explaining the prosecution or declination decisions" he has reached, as required by 28 C.F.R. § 600.8(c). This report is entitled "Report on the Investigation into Russian Interference in the 2016 Presidential Election." Although my review is ongoing, I believe that it is in the public interest to describe the report and to summarize the principal conclusions reached by the Special Counsel and the results of his investigation.
