Here is the video clip:
This first frame is showing consternation and avoidance when Gonzales is mentioning that the reason for the visit to the hospital was supposedly not regarding the terrorist surveillance program that the President announced to the American people. His eyes are closed, and his eyebrows are both raised and pinched together in a sign of fear and melancholy.
The third picture is of Gonzales explaining that there are not any rules to whether or not General Ashcroft can decide if he's well enough to make a decision. When interupted by Senator Specter, Gonzales not only shuts his eyes but also reveals contempt around his mouth - reciprocating the emotional response Specter has to his testimony.
Gonzales reacts here with feigned surprise when Senator Dianne Feinstein asks, "You don't know?" in an almost sarcastically surprised tone to Gonzaeles's statement that he will have to get back to her regarding how many U.S. Attorneys he approved to be fired.
Lastly, we can clearly see by looking at Senator Feinstein's face, that her mouth is showing disgust along with disappointment in response to Gonzales' claims. In other words, she's disillusioned.
