Lawmakers writing the biggest overhaul of financial regulations since the Great Depression may have a stake in the outcome. Eight of 11 senators and six of 22 House members on a conference committee writing the final legislation own stocks in financial companies affected by the legislation, disclosure statements released yesterday show. One senator and nine representatives who also sit on the committee got extensions of the filing deadline and haven't yet disclosed their holdings. "It's always a concern that personal interests influence legislation," said Lisa Gilbert, a lobbyist for the U.S. Public Interest Research Group, a Boston-based organization pushing for stronger financial regulations. Senator Judd Gregg of New Hampshire reported Bank of America stock holdings and a savings account valued between $1 million and $5 million. The 43 negotiators are trying to iron out differences between the House and Senate versions of the legislation as they respond to an economic crisis that forced the U.S. to provide $700 billion in bailout funds for New York-based Citigroup Inc. ... Bank of America Corp. and other banks.
