NATIONAL CITY, Calif. (AP) — An office of the community organization Acorn in San Diego County is trying to recover tens of thousands of documents taken from its garbage by a Republican activist.

It is the latest skirmish in a war between Acorn, which stands for Association of Community Organizations for Reform Now, and conservative critics who accuse it of corruption.

The Republican activist, Derrick Roach, a private investigator who unsuccessfully ran for a State Assembly seat last year, said he took more than 20,000 documents from a caged trash area behind Acorn’s office in National City on Oct. 9.

Some of the documents, later posted on a Web site and displayed Monday at a news conference, appeared to show driver’s licenses and Social Security numbers of Acorn members or job applicants.

There also were immigration records, credit reports, tax returns, credit card statements and bank account numbers, Mr. Roach said Tuesday.

Acorn’s lead organizer in California, Amy Schur, said that the confidential papers had been carelessly included in the trash and that there had been no intent to dump rather than shred them.

“We want to get our property back so that we can properly secure it,” she said.

An Acorn employee filed a report on Monday with the police in National City, a San Diego suburb that has a law forbidding scavenging of trash, Ms. Schur said.

She also contacted the county district attorney’s office asking for help in retrieving documents that contain personal or confidential information. The district attorney’s office said it was looking into the matter.

Mr. Roach said he was not concerned. “They’re not going to get the documents back,” he said.

Mr. Roach said he was shielded by a 1988 Supreme Court ruling that said there was no privacy expectation for garbage. He also said he had contacted the district attorney’s office and sent copies of some documents because he believed Acorn might have broken privacy laws by failing to shred those papers containing personal information.

Mr. Roach and Republican leaders have questioned why the material was dumped just days before investigators with the office of the state attorney general, Jerry Brown, were expected to visit the office.

Mr. Brown’s office began investigating after employees at Acorn offices in San Bernardino and San Diego were caught on video appearing to advise a couple posing as a pimp and prostitute to lie about the woman’s profession to gain financial help for housing.

Ms. Schur said the documents had been thrown out to make room for a new phone bank, not to avoid scrutiny.
