It is my understanding that each public news organization must apply periodically for their license renewal. It might be very rewarding to monitor CNN to find when their license renews and enter an objection to the renewal. They are required by law to inform the public and solicit public comments as to the validity of their right to continue broadcasting.
One individual objection would not make "waves" but if a concentrated effort was exerted by those who advocate a "free press" objections would gain creditability. However, with the liberal politicians in charge, objections would have the same chance to prevail as the proverbial snow ball. Even if efforts to maintain our freedom fails, it behooves each of us to keep the "pot a boiling".
