George HW Bush was a political appointee for what, less than a year, at the CIA. I doubt he has any ties to the CIA.
I think and know a few things which point otherwise. A decade from now it may no longer be the case, but right now there are a lot of seasoned intel folks who hold Bush (Sr.) in very high regard. Much of it has to do with international affairs and not being a modern era opportunist politician. Understanding the hard work and how easily it can be undone by politicians. Bush (sr) was not like that.
