Senate Banking Committee Chairman Christopher Dodd said Wednesday he is worried that the congressional intent of some key aspects of the new, sweeping bank-reform law will be distorted as regulators write rules based on the statute. The 2,300-page statute, which was signed into law by President Barack Obama on July 21, imposes new regulations and restrictions on big banks in the wake of the financial crisis that shook the economy in 2008. Regulators are charged with writing over 200 rules based on the law.
