Willie Brown has always protested to the contrary, but few may listen anymore. San Francisco’s mayor has persistently, even angrily, denied that he was a subject of a public corruption probe launched by the FBI and the U.S. attorney’s office. But a published report Monday detailing subpoenas for records of Brown’s communiqu�s with key figures in the investigation may leave him shouting into the wind.

The San Francisco Examiner reported that a grand jury issued subpoenas to Brown’s office on Jan. 31, asking for records of the mayor’s contacts with businesses and major players in a broad investigation into alleged city contracting abuses.
