In yet another sign of trouble for Air America Radio, the liberal talk network entering its fifth chaotic week on the air, co-founder and chairman Evan Cohen resigned Thursday, as did vice-chairman and investor Rex Sorensen.

The CHICAGO TRIBUNE is planning to report in fresh editions: The company also failed to make its scheduled payroll, leaving its staff roughly 100 radio personalities, writers, and producers unpaid until Thursday.

The departures of Cohen, a former political operative from Guam who was among the network's initial investors, and Sorenson, an investor who owns radio stations in Guam, mark the second executive shake-up at the fledgling network in as many weeks.
