Attorney General Bill Barr could announce as soon as early next week that special counsel Robert Mueller has completed his investigation into Russian interference in the 2016 election, according to a new report.

Barr plans to submit to Congress a summary of Mueller’s confidential report on the two-year investigation, CNN reported Wednesday.

Mueller is required to submit a confidential report to the attorney general after he wraps up his investigation. In the report, Mueller must explain why he decided to bring charges against or not prosecute any matters under investigation.

Rules do not require the report to be shared with Congress or be made public, but Barr is required to inform Congress if the Justice Department prevented Mueller’s team from taking any action.

The news outlet noted that the timing of an announcement could change as it coincides with President Trump’s second summit with North Korean leader Kim Jong Un.

Trump is scheduled to travel to Vietnam next week and Justice Department officials do not want to interfere with the diplomatic efforts.
