Lawmakers in both parties are moving to block a Clinton administration order directing states to help low-income men buy Viagra, the popular but expensive anti-impotency pill.

By voice vote, the House Appropriations Committee approved language Tuesday prohibiting the federal and state governments from paying for the drug with Medicaid, the health care program for the poor.The legislators acted as Wisconsin, New York and perhaps other states considered defying the administration directive. The National Governors Association estimated that Medicaid coverage for Viagra could cost taxpayers $100 million a year.
