Almost 30 key lawmakers helping draft landmark health-care legislation have financial holdings in the industry, totaling nearly $11 million worth of personal investments in a sector that could be dramatically reshaped by this summer's debate.

The list of members who have personal investments in the corporations that will be affected by the legislation -- which President Obama has called this year's highest domestic priority -- includes Congress's most powerful leaders and a bipartisan collection of lawmakers in key committee posts. Their total health-care holdings could be worth $27 million, because congressional financial disclosure forms released yesterday require reporting of only broad ranges of holdings rather than precise values of assets.

Senate Majority Leader Harry M. Reid (D-Nev.), for instance, has at least $50,000 invested in a health-care index, and Sen. Judd Gregg (R-N.H.), a senior member of the health committee, has between $254,000 and $560,000 worth of stock holdings in major health-care companies, including Bristol-Myers Squibb and Merck.

This legislation is simply too important to be tainted by potential conflict of interests. Our elected members of Congress need to be completely transparent about the investments they have in companies who could be affected by their votes.
