Several possibilities exist. Lets run through them to see what we find:
First - GWBush figured out on his own that he now needed a personal attorney. But this is against the prevailing view that GWBush lacks the intellect to make that level of reasoning on his own.
Second - His family was watching out for GWBush and told him to get his own lawyer. Naaa. GWBush does not listen to his Dad. This not in character from his Mother. And family would have told him to keep the hiring of a personal lawyer quiet rather than announce it on the national news.
Third - The US Attorney felt personally compelled by the duties of his office to tell the president to get personal counsel. I think this asks too much of John Ashcroft who is more manipulative in his approaches to these types of problems.
Fourth - White House counsel thought it was a good idea for GWBush to get a personal attorney. No. No. No. Gonzales has shown his methodology. He would go to bat for the president personally and would never suggest that GWBush get his own attorney. That is Gonzales' job and would cut Gonzales off from his political power base that runs through the president.
Fifth - The campaign to re-elect the president told GWBush to get a personal lawyer. No. Never. They would have put a spin on the news and had one of their captive reporters put it out on the air or in print. This is not within their repertoire. They manipulate the news which is not what was done by this announcement.
Sixth - The FBI told GWBush to get a personal lawyer. WHAT !!!! No!!! It is too soon for that. GWBush does not face custody issues and no one says he faces any immediate interrogation.
Seventh - An underling being approached by investigators told GWBush that the memos he never read would soon be revealed to implicate him in the disclosure of intelligence information, i.e., a real threat of disclosure of criminal conduct. Possible.
Underlings are being investigated. Do these underlings make decisions without even nominal consultation with GWBush, or does GWBush ignore their memnos like he did the pre 9/11 memos on terrorist activities? This is the only escape for underlings involved in the disclosure of intelligence information, that they did it with the implied consent and authority of their superiors, who must now also be warned about the pending disclsoure.
If the last senario seven is the most probable and is true, then this means that there is pressure being placed on GWBush from the investigation itself, which can be powerful. This is especially true if the usual government lawyers are now disqualified from participating in the investigation because of a conflict of interest between their allegiance to GWBush and their allegiance to the USA.
I have presented seven alternative sources of the pressure on GWBush to obtain personal counsel. Are there other possible sources that I have ignored? The motiviation to obtain personal counsel indicates some of the reasons for retaining personal counsel.
I believe that the key for determining why GWBush obtrained personal counsel lies in the fact that he publically disclosed on national television that he was retaining a personal attorney. This is unusal behavior and suggests matters beyond his control. Most people seriously needing their own personal attorny do not broadcast that information.
If the above analysis is incorrect, then who told GWBush to get hiis own lawyer?
