In Washington, a former co-chair of the Republican Party has been appointed to head the Corporation for Public Broadcasting. Patricia Harrison will serve as CPB’s president and chief executive even though she has no significant broadcasting experience. Harrison’s appointment comes just days after 16 Democratic Senators called on the chair of the CPB — Kenneth Tomlinson — to resign for politicizing public broadcasting. CPB Board member Beth Courtney voted against Harrison’s appointment. She said ’’I was asked by hundreds of colleagues in public broadcasting not to select someone who was in a partisan position. The stations are very upset.”
