From Yahoo! news:

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…

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.
