Those are all generic network switchboard numbers, not the numbers for the actual news divisions. The Kerry Kamp isn't going to get far with those. They'll just be directed to voicemail boxes that never get listened to.
I forwarded to one person in the news division so far (at MSNBC). I have been told that I could talk to more if it was morning. These numbers may be better than you think. (Although the MSNBC person did say that she would share my comments with someone in national news, and then hung up on me.) I may have better luck tomorrow.
Try this idea as well
