I can't even begin to imagine the outrage if this were a republican. WASHINGTON â Secretary of State nominee Hillary Rodham Clinton intervened at least six times in government issues directly affecting companies and others that later contributed to her husband's foundation, an Associated Press review of her official correspondence found. The overlap of names on former President Bill Clinton's foundation donor list and business interests whose issues she championed raise new questions about potential ethics conflicts between her official actions and her husband's fundraising. The AP obtained three of the senator's government letters under the Freedom of Information Act. During Clinton's confirmation hearing Tuesday, Sen. Richard Lugar of Indiana, the Foreign Relations Committee's senior Republican, said the foundation's charitable efforts "should not be a barrier to Senator Clinton's service," but he acknowledged the potential that conflicts of interest might arise: "Work of the Clinton foundation is a unique complication that will have to be managed with great care and transparency." Under an agreement with President-elect Barack Obama, Bill Clinton recently released the names of donors to his foundation, a nonprofit that has raised at least $492 million â including millions from foreign governments â to fund his library in Little Rock, Ark., and charitable efforts worldwide on such issues as AIDS, poverty and climate change. Lugar told Sen. Clinton on Tuesday that her husband's foundation should not accept any more contributions from foreign governments. The letters and donations involve pharmaceutical companies and telecommunications and energy interests. An aide to the senator said she made no secret of her involvement in many of the issues. Bill Clinton's foundation declined to say when it received the donations or precisely how much was contributed. "Throughout her tenure, Senator Clinton has proven that she acts solely based on what she believes is best for the state and people she represents, without consideration to any other factor," said spokesman Philippe Reines. "In these instances, she was doing what the people of New York elected her to do: Work hard on the issues of importance to them." Hillary Rodham Clinton and the Clinton Foundation both declined to answer questions about whether the senator tried to step away from issues directly affecting donors to her husband's charity, and whether the foundation tried to screen out money from those on whose issues the senator had intervened. "Generally, through a combination of rigorous adherence to Senate and FEC income and asset disclosure rules, coupled with the voluntary and unprecedented release of the names of every single Foundation supporter since its inception, the Clintons are by far the most financially transparent former first couple in American history," Reines said. Sen. Clinton wrote to the Federal Communications Commission in February 2004 expressing concern that changes to competitive local exchange carrier access rates could hurt carriers such as New York-based PAETEC Communications. PAETEC's chief executive is Arunas Chesonis, whose family and charity later contributed to the Clinton foundation. Sarah Wood, executive director of the Chesonis Family Foundation, was invited by a part of the Clinton Foundation, the Clinton Global Initiative, to join the initiative after it was established in 2005, Wood said Monday. The Chesonis family personally paid $15,000 for Wood's membership in CGI in September 2007, and the Chesonis foundation paid $20,000 for it in March 2008, Wood said. The Chesonis Family Foundation made a $10 million pledge last May to the Massachusetts Institute of Technology for solar energy research, meeting Wood's commitment to the Clinton Global Initiative to act on a project, Wood said. Wood said the Chesonis foundation was unaware of the senator's letter to the FCC on the PAETEC issue and didn't have any contact with her office. PAETEC spokesman Christopher Muller said PAETEC had no involvement in the Chesonis donations to the Clinton foundation. PAETEC asked Clinton to intervene with the FCC on its behalf, he said. "Yes, PAETEC feels strongly that a competitive telecom environment is in the best interests of New York businesses and consumers," Muller wrote in an e-mail to the AP. "PAETEC has petitioned numerous elected officials in the markets which we serve in an effort to retain the spirit of the Telecom Act of 1996." The issue is still pending at the FCC, and PAETEC remains involved in it, Muller said. Pharmaceutical company Merck & Co. is also a member of the Clinton Global Initiative, company spokeswoman Amy Rose said. Merck joined CGI in 2006, when dues were $15,000, and also was a member in 2007 and in 2008, when membership dues rose to $20,000. As part of its commitment to CGI, Merck sponsors public health initiatives around the world, Rose said. Merck joined CGI on its own initiative, she said. Sen. Clinton wrote a November 2005 letter to Health and Human Services Secretary Mike Leavitt urging approval of the human papillomavirus vaccine. Merck applied in December 2005 for approval of its HPV vaccine, Gardasil, and the vaccine was approved for use in females ages 9 to 26. Merck is still seeking approval for use in older women, Rose said. Rose said Merck's participation in the Clinton Global Initiative was unrelated to Sen. Clinton's letter. Merck didn't communicate with Clinton or her office about its HPV vaccine and was unaware of her letter before it was sent, Rose said. Another letter involved an issue important to Barr Laboratories. Sens. Clinton and Patty Murray, D-Wash., wrote to Leavitt in August 2005 urging that "science, not politics" guide the agency and "that a decision be brought swiftly on Plan B's application." Leavitt's office described the Clinton letter as pertaining to Barr's application for Plan B, the emergency contraceptive also called the morning-after pill. Barr Laboratories gave $10,001 to $25,000 to the Clinton foundation, the charity's donor list shows. Barr joined the Clinton Global Initiative in April 2007, spokeswoman Carol Cox said. Cox didn't comment on Clinton's letter. Several of the letters involve issues directly affecting KeySpan Corp., the energy company now known as National Grid. KeySpan didn't ask the senator to intervene and had no communication with her office about its later donations to the Clinton foundation, said company spokesman Chris Mostyn. KeySpan joined the Clinton Global Initiative in 2007 because it wanted to become involved in the climate change issue, Mostyn said. KeySpan paid $15,000 for its membership in 2007 and $20,000 for 2008, Mostyn said. Clinton joined several other members of Congress from New York in February 2003 asking the Commerce Department to consider an appeal by Islander East, a limited liability company formed by subsidiaries of KeySpan Energy and another company, to build a natural gas pipeline to serve Connecticut, New York City and Long Island, N.Y. Clinton and the other lawmakers wanted the Commerce Department to overturn the Connecticut Department of Environmental Protection's determination that Islander East's pipeline plan was inconsistent with the state's coastal zone management program. Sen. Christopher Dodd, D-Conn., and other Connecticut lawmakers wrote to Commerce urging denial of Islander East's appeal. Clinton earlier wrote to the Long Island Power Authority and to KeySpan urging them to consider the modernization of KeySpan's New York power plants. Her letter in June 2002 offered her help on the issue. Also in 2002, Clinton wrote the federal government letters on the natural gas Millennium Pipeline Project in which KeySpan was involved, urging an extension of a deadline for public comment and forwarding information on route alternatives. Mostyn said KeySpan didn't ask Clinton to get involved in the issues. The Millennium Pipeline began commercial operations in December, the Islander East project is on hold due to Connecticut's rejection of permits, and the company is working with the Long Island Power Authority to study power plant modernization, he said.
