The president of the Corporation for Public Broadcasting has resigned less than a year into her tenure, and will be replaced on an interim basis by a close associate of the controversial former FCC chairman Michael Powell. Kathleen Cox was groomed for years to lead CPB, but she apparently fell victim to an increasingly political workplace as conservative politicians ratcheted up their anti-PBS rhetoric over the last year. One observer has described Cox as “an apolitical bureaucrat in an incredibly polarized agency,” an identity which may have been at odds with CPB’s desire to ingratiate itself to its critics in Congress.
