From pre and post CIA documents ( those made public and those leaked) it is apparent that Bush "knew" about the plans for the attack , but he and the Cheney-Rice-Rumsfield secrecy group ignored the warnings..
""The attack will be spectacular and designed to inflict mass casualties against U.S. facilities or interests. Attack preparations have been made. Attack will occur with little or no warning."
- CIA Intelligence Report for President Bush, July, 2001 (60 Days Prior to 9/11)
This was given to Bush by George Tenet, now he is replaced by Goss, probably because of this leak and his refusal to be a good "team player"
"attempt to formulate policy" is not at all the job of our spy agencies, it is to report only and all information they have on critical subjects to the president and his cabinet..... unsexed
The CIA and FBI are not "employees" of any president, and what information they give is not a commodity to use by a president to sell for a profit, or use as political capital to spend as he might see fit.
The memo leak shows perfectly well who Goss works for...and who he will show allegiance,
