From this story on Congress' look-see at the U.S. Attorney firings:
After the hearing, Watt said he thought Goodling's answers about how Wagoner stayed off the list showed "the shallowness" of how those decisions were made."I think the more interesting questions are how she got on the list and how there came to be a list in the first place," Watt said.
So far, none of the witnesses who have testified before Congress have shed light on that topic. "This is honestly something that when it started I didn't think it would have legs or go anywhere," Watt said. "But every time you peel back another layer, it smells worse."
