copyright 2009, The Washington Post WASHINGTON -- 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 report, disclosed on a publicly accessible computer network, was made available to The Washington Post by a source familiar with such networks. The ethics committee is one of the most secretive panels in Congress, and its members and staff members sign oaths not to disclose any activities related to its past or present investigations. Watchdog groups have accused the committee of not actively pursuing inquiries; the newly disclosed document indicates the panel is conducting far more investigations than it had revealed. Shortly after 6 p.m. Thursday, the committee chairman, Zoe Lofgren, D-Calif., interrupted a series of House votes to alert lawmakers about the breach. She cautioned that some of the panel's activities are preliminary and not a conclusive sign of inappropriate behavior. 'No inference should be made as to any member,' she said. Rep. Jo Bonner of Albama, the committee's ranking Republican, said the breach was an isolated incident. The 22-page 'Committee on Standards Weekly Summary Report' gives brief summaries of ethics panel investigations of the conduct of 19 lawmakers and a few staff members. It also outlines the work of the new Office of Congressional Ethics, a quasi-independent body that initiates investigations and provides recommendations to the ethics committee. The document indicated that the office was reviewing the activities of 14 other lawmakers. Some were under review by both ethics bodies. Many of the broad outlines of the cases are known -- the committee announced over the summer that it was reviewing lawmakers with connections to the now closed PMA Group, a lobbying shop. But the document indicates that the inquiry was broader than initially believed. It included a review of seven lawmakers on the House Appropriations defense subcommittee who have steered federal money to the firm's clients and have also received large campaign contributions. The document also disclosed that: --Ethics committee staff members have interviewed House Ways and Means Chairman Charles Rangel, D-N.Y., about one element of the complex investigation of his personal finances, as well as the lawmaker's top aide and his son. Rangel said he spoke with ethics committee staff members regarding a conference that he and four other members of the Congressional Black Caucus attended last November to St. Maarten. The trip initially was said to be sponsored by a nonprofit foundation run by a newspaper. However, the three-day event, at a luxury resort, was underwritten by major corporations such as Citigroup, Pfizer and AT&T. Rules passed in 2007, shortly after Democrats reclaimed the majority following a wave of corruption cases against Republicans, bar private companies from paying for congressional travel. Rangel said he has not discussed other parts of the investigation of his finances with the committee. 'I'm waiting for that, anxiously,' he said. --The Justice Department has told the ethics panel to suspend a probe of Rep. Alan Mollohan, D-W.Va., whose personal finances federal investigators began reviewing in early 2006 after complaints from a conservative group that he was not fully revealing his real estate holdings. There has been no public action on that inquiry for several years. But the department's request in early July to the committee suggests that the case continues to draw the attention of federal investigators, who often ask that the House and Senate ethics panels refrain from taking action against members whom the department is already investigating. Mollohan said that he was not aware of any ongoing interest by the Justice Department in his case and that he and his attorneys have not heard from federal investigators. 'The answer is no,' he said. --The committee on June 9 authorized issuance of subpoenas to the Justice Department, the National Security Agency and FBI for 'certain intercepted communications' regarding Rep. Jane Harman, D-Calif. As was reported earlier this year, Harman was heard in a 2005 conversation agreeing to an Israeli operative's request to try to obtain leniency for two pro-Israel lobbyists in exchange for the agent's help in lobbying House Speaker Nancy Pelosi, D-Calif., to name her chairman of the intelligence committee. The department, a former U.S. official said, declined to respond to the subpoena. Harman said that the ethics committee has not contacted her and that she has no knowledge that the subpoena was ever issued. 'I don't believe that's true,' she said. 'As far as I'm concerned, this smear has been over for three years.' In June 2009, a Justice Department official wrote in a letter to an attorney for Harman that she was 'neither a subject nor a target' of a criminal investigation. Meanwhile, the House ethics committee said Thursday that it is ending a probe of Rep. Sam Graves, R-Mo., after finding no ethical violations, and that it is investigating the financial connections of two California Democrats. One of them, Rep. Maxine Waters, a high-ranking member of the House Financial Services Committee, came under scrutiny after she reportedly helped arrange a meeting between federal regulators and executives at OneUnited Bank. Waters' husband, Sidney Williams, holds at least $250,000 in its stock. The other, Rep. Laura Richardson, may have failed to mention property, income and liabilities on financial disclosure forms. The committee's review of investigations became available on file-sharing networks because of a junior staff member's use of the software while working from home, Lofgren and Bonner said in a statement issued Thursday night. The staffer was fired, a congressional aide said. The committee 'is taking all appropriate steps to deal with this issue,' they said, noting that neither the committee nor the House's information systems were breached in any way. House administration rules require that if a lawmaker or staff member takes work home, 'all users of House sensitive information must protect the confidentiality of sensitive information' from unauthorized disclosure. Leo Wise, chief counsel for the Office of Congressional Ethics, declined comment, citing office policy against confirming or denying the existence of investigations. A Justice Department spokeswoman declined to comment, citing a similar policy. Staff writers Carol D. Leonnig and Joby Warrick and staff researcher Julie Tate contributed to this report.
