Mississippi regulators are looking into the operations of a California man who is under investigation for violating federal law involving telemarketing solicitations for credit cards.

The Public Service Commission's action comes on the heels of a case filed by the Federal Trade Commission and the U.S. Department of Justice against Roy Cox, Jr., and his companies.

Northern District PSC member Brandon Presley says the allegations against Cox, of Santa Ana, Calif., and his companies involve possible violations of the Mississippi No-Call law for illegal robo-calls.

Each violation carries a fine of up to $5,000.

Presley says the PSC and FTC have traded information on their separate investigations.
