Per the Washington Post:
… The cost is not necessarily out of line with prior special investigations, and the documents note that Mueller is reporting what his work has caused other Justice Department components to spend — which previous special counsels have not. Mueller reported about $4.5 million in expenditures from October through March, and indicated his investigation caused other Justice Department components to spend about $5.5 million.
The money that Mueller spent directly came from an indefinite appropriation for independent counsels, which the Justice Department determined could be used to fund Mueller’s work. The department said the other money would have been spent by Justice Department components for the investigations “irrespective of the existence” of the special counsel’s office.
From October through March, Mueller, who has a team of 17 lawyers, spent $2.7 million on personnel costs, the new documents show. He also spent more than a half-million dollars on travel and more than $880,000 on rent, communications and utilities, the documents show.
By comparison, Lawrence E. Walsh, the prosecutor who investigated Reagan administration officials in the Iran-contra affair, spent $47.4 million during his eight-year investigation. Former independent counsel Kenneth W. Starr spent more than $52 million investigating President Bill Clinton, and the five independent counsels appointed to look into various Clinton-related matters during the 1990s spent more than $100 million.
