Washington CNN  — 

The Mueller investigation cost a total of almost $32 million through the course of the probe, according to newly released figures from the Justice Department.

That accounting tallied both the amount former special counsel Robert Mueller borrowed from other Justice Department components that weren’t under his direct control, as well as his office’s direct expenses.

In all, Mueller directly spent about $16 million on his office over two years.

The total amount of the office of special counsel’s expenditures for its final six months, from October through May, was $6.5 million, according to the accounting statement released Friday.

That figure breaks down into two parts – Mueller’s direct expenses and his indirect expenses. In his last six months before the office closed in late May, the special counsel’s office directly spent $4.1 million, mostly on its personnel, according to the statement Friday.

In his last six months, Mueller had begun to involve other US attorney’s offices in cases he had investigated, and several of his prosecutors had left the office before its official closure. At the same time, the remaining attorneys were working on finalizing the Mueller report.

Mueller found several examples of Russian efforts to sway the election for the Trump campaign, but did not find evidence that the Trump campaign knowingly took part in the allegedly criminal conspiracy, according to his 448-page report released in April.
