Reuters, citing three U.S. officials, reported on the matter Monday, noting that the funding for Mueller's office was not addressed in the new budget requests issued by the White House and Department of Justice. The officials told the news outlet that Mueller's team is still being funded by the Treasury Department under specific regulations administered by the Justice Department.

“The Special Counsel is funded by the Independent Counsel appropriation, a permanent indefinite appropriation established in the Department’s 1988 Appropriations Act,” a Justice Department spokesman said.

The news about the funding for Mueller's investigation comes as speculation increases that his extensive probe is reaching its conclusion. Multiple reports have indicated Mueller will deliver a report to Attorney General William Barr detailing his investigation in the coming weeks.

Mueller reported spending about $9 million during the last fiscal year, according to Justice Department documents obtained by Reuters. It is unclear how much he has spent in the current fiscal year.

According to regulations, Mueller is required to report to the attorney general the status of his investigation at the start of each fiscal year. It is during this time that he can provide budget requests.

It is unclear if Mueller is looking to make a request for fiscal 2020, according to Reuters.

Trump has repeatedly derided Mueller's investigation, often calling it a "witch hunt."
