NY lawmaker seeks crackdown on performance drugs

A New York state lawmaker wants to ban a popular over-the-counter, muscle-building drug following cyclist Lance Armstrong's confession of using the dangerous supplements to win the Tour de France.

Sen... Jeffrey Klein is scheduled to call for the ban Thursday. He's the leader of the Independent Democratic Conference that shares the chamber's majority control.

Klein says hidden camera footage shows vitamin store employees downplaying the risks of the supplements to teenagers.

Klein seeks a state ban on an active ingredient in most of the best-selling muscle-building products sold at vitamin and health food stores.

Klein is holding his press conference in Manhattan with fitness experts.
