CHARLESTON, W.Va. (AP) — The executive director of West Virginia Public Broadcasting has stepped down after one year on the job, the latest sign of upheaval at a news outlet recently shaken by a reporter's allegation that she was fired for writing an unfavorable story about a division of the state health department. Butch Antolini, former communications director for Gov. Jim Justice and the state Department of Agriculture, didn't give a reason for his resignation in a brief letter submitted to the board chairman of the West Virginia Educational Broadcasting Authority on Friday.
