WASHINGTON (AP) — The Latest on special counsel Robert Mueller’s investigation (all times local):

5:15 p.m.

Special counsel Robert Mueller’s report concluding the Russia investigation was delivered by a security officer early Friday afternoon to the office of Deputy Attorney General Rod Rosenstein.

That’s according to Justice Department spokeswoman Kerri Kupec. It was then delivered within minutes to Attorney General William Barr.

The White House was notified around 4:35-4:40 p.m. that the Justice Department had received the report.

The letter was scheduled to be delivered at 5 p.m. to staff members on Capitol Hill.

Rosenstein was expected to call Mueller on Friday to thank him for his work in the last two years.

Attorney General William Barr says he could update Congress as early as this weekend about special counsel Robert Mueller’s findings in the Russia investigation.

The Justice Department confirmed late Friday that Barr received Mueller’s final report. The report concludes Mueller’s nearly two-year-long investigation of Russian election interference and possible coordination with President Donald Trump’s campaign.

Special counsel Robert Mueller has concluded his investigation into Russian election interference and possible coordination with associates of President Donald Trump.

The Justice Department says Mueller delivered his final report Friday to Attorney General William Barr, who is reviewing it.

Mueller’s report, still confidential, sets the stage for big public fights to come. The next steps are up to Trump’s attorney general, to Congress and, in all likelihood, federal courts.

It’s not clear how much of the report will become public or provided to Congress. Barr has said he will write his own report summarizing Mueller’s findings.

The nearly two-year probe has shadowed Trump’s presidency and resulted in felony charges against 34 people including six people who served on Trump’s campaign.
