A Justice Department report released Tuesday shows Special Counsel Robert Mueller’s investigation spending $3.2 million between its formation in mid-May and the end September.

The bulk of those expenditures are on personnel, with $1.2 million spent on DOJ employees reassigned to Mueller’s team and about $500,000 on others brought in on the investigation.

A release from the Special Counsel’s Office says that new expenditure reports will be released every six months, with the next one coming on March 30, 2018.

Beyond the $3.2 million being spent directly by Mueller’s team, an additional $3.5 million was spent by other entities in the DOJ that are involved in investigations supporting Mueller’s probe. That spending “approximates expenditures the components would have incurred for the investigations irrespective of the existence of the SCO,” the report said.
