Amid the uproar over the Republican Party’s attempt to cripple the Office of Congressional Ethics, a little-noticed rule change was passed that guts an essential element of government oversight.

The rules package included a sentence that read: “Records created, generated, or received by the congressional office of a Member…are exclusively the personal property of the individual Member…and such Member…has control over such records.”

The change, first pointed out by OpenSecrets.org and reported by the Fiscal Times on Monday, effectively means that some documents are no longer the property of the U.S. government, giving lawmakers the ability to hide critical information from an oversight investigation.

“Who cares whether a congressional office’s budget documents, maintained at taxpayer expense, belong to each individual member, rather than Congress as a body?” asked Ashley Balcerzak, money-in-politics reporter for OpenSecrets. “Maybe the Justice Department, for one. In investigating allegations of public corruption or misuse of funds, criminal investigators frequently need to subpoena such records.”

Balcerzak explained:

“There’s no cop on the beat,” Sheila Krumholz, executive director of the Center for Responsive Politics, told the Fiscal Times. “We’ve lost a critical element of independent oversight.” 

“Why on earth would Congress now create barriers to investigation and subpoenas of a member’s spending records?” Krumholz added. “This only benefits the incumbent politicians who passed this rule and those who would flout it, not the system and certainly not the public.”

House Republicans made a blatant attempt to gut oversight last week when they voted to “neutralize and reconfigure the Office of Congressional Ethics by stripping its independent authority and making it subservient to the very members of congress it was designed to oversee,” as Common Dreams reported at the time. But that effort was thwarted after widespread outrage forced lawmakers to back-track on the plan.
