From the video:
"We have seen an unprecedented attempt by the current administration to attack its predecessor. Traditionally, when we have a change in administration the new administration may make an occasional reference to the previous administration but it's sort of like that was yesterday let's look forward. Instead this administration has almost daily I mean there has not been a week go by where there has not been several attacks made on its predecessor.
Finally, Dick Cheney decided that while he would like to stay on the sideline and keep a low profile that somebody had to stand up and set the record straight. And, I for one is glad that he did so."
