Cheney did address the major questions head on.
Why did he wait? The shooting was not a national security matter. It was a personal matter. It was an accident in someone's farm. No laws were broken.
Why did he go to FOX News? My guess is that VP Cheney is comfortable with Brit Hume. Why not? Hume is a serious reporter who does not walk around promoting an agenda. Hume is a conservative but he is also better known as a respected journalist.
Furthermore, VP Cheney went to FOX because they have the best ratings. Do you want to reach people? Go to FOX.
Hopefully, this mess will pass soon and we can get back to the Iran crisis and other issues of greater importance.
