The telemarketing industry is widening its legal challenge to the government's National Do-Not-Call list.
The industry is suing a second federal agency over the call-blocking service, which telemarketers say will ruin their business and put up to two million people out of work.
An industry group had sued the Federal Trade Commission in January to try to stop the list. Now it's asking a federal court to reject new rules set by the Federal Communications Commission.
The FCC added its authority to the list to close regulatory loopholes and block calls from certain industries -- including airlines, banks and telephone companies.
The head of the American Teleservices Association calls the government agencies' actions "regulatory overkill."
