The latest revelation, that a supposedly independent researcher hired by Tomlinson without the approval of the corporation to investigate supposed liberal bias in PBS’s newsmagazine, Now with Bill Moyers, “worked for 20 years at a journalism center founded by the American Conservative Union and a conservative columnist,” is being investigated by CPB’s inspector general. Meanwhile, one sitting U.S. Senator is openly calling for Tomlinson’s resignation.
