WASHINGTON (AP) – 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.

Attorney General William Barr says he may send Congress summary of Mueller’s findings by this weekend.

President Donald Trump’s lawyers say they are “pleased” that special counsel Robert Mueller has delivered his report on the Russia investigation.

Rudy Giuliani and Jay Sekulow issued their joint statement within minutes of Attorney General William Barr’s letter to key members of Congress confirming the delivery and suggesting he could update lawmakers as soon as this weekend.

They say: “We’re pleased that the Office of Special Counsel has delivered its report to the Attorney General pursuant to the regulations. Attorney General Barr will determine the appropriate next steps.”

Mueller’s report, still confidential, sets the stage for big public fights to come, including in all likelihood, in federal court. It’s not clear how much of the report will become public or provided to Congress.
