Where did you see this interview with Matalin and what did she say? Because no one can find a link that she works for the VP in an official or even unofficial capacity.
I've called a former boss of mine when his wife had surgery. What does it mean? Not a heck of a lot except that I care about them as a family.
Sure, we all call friends and family. But, before most folks, even in the WH, knew that the VP had even shot someone, she was on the phone with him at the ranch. Later, she was talking to the press about his utter lack of any culpability.
If you want to believe that this does not serve as any indication that she still advises and works with the VP on PR matters, that's fine. We both know that there are many, many people working in private sector positions that serve such roles, and Matalin continues to be introduced that way. I do not claim she has an 'official' position in his office. But that doesn't mean she doesn't still go out and work the press for him.
Mr. Cheney's host, the WH Press Secretary, and his former communications director have all spoken publicly about Mr. Whittington's role in getting himself shot. Are you aware of any statement from any person affiliated with the VP in any way regarding the VP's role in getting Mr. Whittington shot?
I believe he is probably going to do it himself, at some point. Doing it before he is urged to do so would've been better.
