I don’t believe Haig was attempting to usurp control over the Veep, or SOH, or anyone.
The White House was the subject. Who is directing things at the WHITE HOUSE since Bush was away?
Haig was correct. He was.
It was way overblown. The MSM was trying to make it look like Haig was going all "Seven Days in May".
You are absolutely correct. There are at least two sides to every story and Haig’s book makes clear what he said and why.
