A jurisdictional squabble between House committees may administer the coup de grace to the Bush Administration's broad bank-reform legislation this year. Banking Committee Chairman Henry B. Gonzalez (D-Tex.) is complaining bitterly that the rival Energy & Commerce Committee overstepped its bounds in writing its own version of the bill, which would allow banks to enter such new businesses as securities underwriting. In theory, it's up to the House Rules Committee to come up with a unified version of the legislation. So to protect his panel's territory, Gonzalez may opt for a narrower bill that infuses new money into the Bank Insurance Fund without overhauling the financial-services industry.
