For somebody that hasn't looked at the video, it's now well below the top of the page.
For somebody that is somewhat familiar with this situation there is no new information in the video.
It appears that H.E. Cummins was fired to make room for an attorney that had spent most of his career as a Republican operative. There is no appearance here that Cummins was replaced for other than a straightforward political purpose, although it might be argued that Griffen would have had a better understanding of the administrations priorities than Cummins and thus replacing Cummins was just the legitimate effort by the administration to see their legitimate priorities emphasized by the US Attorney.
The problem I see for the administration is that in this particular case there seems to be strong evidence that the administration intended to use the patriot act to make a US Attorney appointment without Senate approval. Sampson, yesterday, testified that while he thought the administration should do that, Gonzales among others thought it was a bad idea and that they wouldn't and didn't do it.
But it looks like that is exactly what they did here. Certainly Griffen thought that was what they were doing. Certainly the administration knew that Griffen wouldn't win approval for a US Attorney job.
Right now, despite how scummy the replacement of Cummins looks for the administration, if there is any prosecutable misconduct with the attorney firings, it probably isn't with this case. The firing of Lam and Iglesias may have been done to obstruct justice and to unduly influence US prosecutors for political purposes. I think it is very likely that this was done, but I think those charges are a very long way from being proved.
