The embattled head of Washington public radio station WAMU has been fired. Susan Clampitt, who had directed the station since June 2000, had come under fire from current and former staff members, donors and volunteers. They questioned her financial management of the station and her managerial style, which had led to widespread staff disgruntlement.” WAMU ran through more than $4 million in cash reserves in the process in the past three years as spending jumped 110 percent from 2000 to 2002.
