The new chairman of the Corporation for Public Broadcasting is aggressively pushing PBS to provide more conservative political voices in its programming, citing what he believes is years of “liberal bias” in news programs and documentary series. PBS’s outgoing president is firing back, accusing CPB of interfering with the network in an inappropriate way. Others have noted that the new chairman appears to be driven by an obsessive and “vehement dislike of journalist Bill Moyers,” who recently left PBS, and that he actually hired outside consultants to monitor the political leanings of guests on Moyers’s news/interview program, Now.
