"House ethics investigators have scrutinized the activities of more than 30 lawmakers and several aides in inquiries about issues including defense lobbying and corporate influence peddling, according to a confidential House ethics committee report prepared in July," the Washington Post reports.
"The report appears to have been inadvertently placed on a publicly accessible computer network, and was provided to The Washington Post by a source not connected to the congressional investigations. The committee said Thursday night that the document had been inadvertently released by a low-level staffer."
