No, it's not the CPUSA, but it's close: "Concerns Arise at A.C.L.U. Over Document Shredding":

The American Civil Liberties Union has been shredding some documents over the repeated objections of its records manager and in conflict with its longstanding policies on the preservation and disposal of records.

The matter has fueled a dispute at the organization over internal operations, one of several such debates over the last couple of years, and has reignited questions over whether the A.C.L.U.'s own practices are consistent with its public positions.

The organization has generally advocated for strong policies on record retention and benefited from them, most recently obtaining and publicizing documents from the government about prisoners at Guantanamo Bay, Cuba.

The debate over the use of shredders is reminiscent of one late last year over the organization's efforts to collect a wide variety of data on its donors, even as it criticizes corporations and government agencies for accumulating personal data as a violation of privacy rights...

...The organization is sensitive to such leaks, given past government scrutiny of its membership...

When I saw this developing at Drudge I was - needless to say - very, very excited. However, this turned out to be mainly an inside-the-ACLU report, much like, say, the Village Voice would write about the turmoil inside the CPUSA or some other similar organization.

I want dirt, Drudge. Real, dirty, hardcore dirt that will finally send the ACLU back to Russia.
