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. The family of Rep. Jane Harman (D-Calif.), a senior member of the House Energy and Commerce Committee drafting that chamber's legislation, held at least $3.2 million in more than 20 health-care companies at the end of last year. If someone is going to be substantially enriched by the consequences of the vote, particularly if it represents a meaningful amount of their net worth, then there is a problem," said Harlan Krumholz, a professor of medicine at Yale University.
