Government watchdog Judicial Watch filed a Freedom of Information Act lawsuit Thursday seeking details about the cost of Special Counsel Robert Mueller's security detail. The move comes after the Department of Justice ignored a FOIA request submitted earlier this year on the topic.

“The Justice Department, the FBI and Special Counsel Mueller’s continue to operate as if they are above the law,” Judicial Watch President Tom Fitton released in a statement. “The American people have a right to know how much taxpayer money is being thrown at Mueller’s massive investigation. Judicial Watch has never before seen this level of secrecy surrounding the operation of a special or independent counsel.”

The lawsuit seeks "all records reflecting expenses incurred by, and disbursements of funds for, the security detail for Special Counsel Robert Mueller" and "all logs maintained by the security detail assigned to Special Counsel Robert Mueller."

The Special Counsel released Q3 costs for the probe into the 2016 presidential election on December 14, bringing the total to at least $12 million.

Rumors continue to swirl in Washington about when Mueller will end his probe. In the meantime, Judicial Watch is seeking information on a number of other issues related to the Special Counsel investigation.
