WASHINGTON (AP) -- The National Security Agency was involved in the surveillance of an American law firm while it represented a foreign government in trade disputes with the United States, The New York Times reported in a story based on a top-secret document obtained by former NSA systems analyst Edward Snowden.
The February 2013 document shows that the Indonesian government had retained the law firm for help in trade talks, the Times reported in a story posted on its website Saturday. The law firm was not identified in the document, but the Chicago-based firm Mayer Brown was advising the Indonesian government on trade issues at the time, according to the newspaper.
The document itself is a monthly bulletin from an NSA liaison office in Canberra, the capital of Australia. The NSA's Australian counterpart, the Australian Signals Directorate, had notified the NSA that it was conducting surveillance of the talks, including communications between Indonesian officials and the American law firm, and offered to share the information, the Times reported.
Liaison officials asked the NSA general counsel's office, on behalf of the Australians, for guidance about the spying. The bulletin notes only that the counsel's office "provided clear guidance" and that the Australian eavesdropping agency "has been able to continue to cover the talks, providing highly useful intelligence for interested U.S. customers," according to the Times story.
The NSA and the Australian government declined to answer questions about the surveillance, the Times reported.
