(CNSNews.com) -- The government watchdog group Judicial Watch is suing the Department of Justice (DOJ) to release its information on the budget for Special Counsel Robert Mueller's investigation into alleged Russian collusion with the 2016 Trump campaign.

The Freedom of Informaiton Act (FOIA) lawsuit was filed in federal court because the DOJ did not respond to a July 10, 2017 request from Judicial Watch seeking information on the special counsel's budget, which is paid for by U.S. taxpayers.

“The Mueller special counsel investigation is growing with seemingly little concern about costs to the taxpayer,” said Judicial Watch President Tom Fitton. “Is the Justice Department hiding basic budget information about the Mueller special counsel operation because taxpayers and Congress would be outraged by the costs? "

"Mr. Mueller is not above the law and he shouldn’t be able to keep his budget secret," said Fitton. "No one else in D.C. seems to be providing oversight of the Mueller juggernaut, so once again it is up to the citizens group Judicial Watch to go to court and demand accountability.”

The FOIA action requests the following:

1. A copy of the budget prepared and submitted by Robert S. Mueller III or his staff in his capacity as appointed “Special Counsel to oversee the previously-confirmed FBI investigation of Russian government efforts to influence the 2016 presidential election and related matters.” Temporal scope of this request is from 17 May 2017 to 10 July 2017.

2. A copy of all guidance memoranda and communications by which the Justice Management Division will review the Special Counsel’s Office’s “Statement of Expenditures” prior to or for the purpose of making each public. Temporal scope of this request is from 1 June 2017 to present.

3. A copy of each document scoping, regulating, or governing the Special Counsel’s Office appointed under the leadership of Mueller III. Temporal scope of this request is from 17 May 2017 to present.
