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 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.
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."
