The Equal Employment Opportunity Commission has filed a sex discrimination lawsuit against a Baltimore TV station accused of firing an anchorwoman because she demanded the same pay as her male counterparts.

Officials said the lawsuit Monday against WBAL and parent company Hearst Corp. is the first such action by the federal agency against a TV station.EEOC Chairman Evan Kemp Jr. said the agency found that former Ruth Ann "Rudy" Miller was paid less than her male counterparts for similar duties and fired in 1989 because she demanded equal pay.
