President Clinton, under heavy fire from governors and mayors for what they called a power grab, has suspended an executive order on federalism. Quietly signed in May, the order was meant to replace an earlier Clinton directive as well as one signed by President Reagan on federal intervention in state and local matters. Critics faulted the Clinton order for laying out multiple justifications for federal intervention and pre-emption, rather than stressing deference to state and local officials. The president's action Wednesday suspended the order indefinitely. For good measure, the House voted 417-2 Wednesday night to nullify the executive order.
