What is it you think is debunked, exactly? General Ham twice offered military support to Ambassador Stevens, and Stevens declined. This is confirmed in the new Senate Intelligence Committee report (page 20). The fact that
USA Today doesn't mention this is unsurprising. They are trying to summarize a long report in something easy to read.
Note that I don't blame Stevens for his own death. Lacking evidence to the contrary, I'll presume he had good reasons for turning Ham down. Nonetheless, it raises an interesting question I've asked several times before (with predictable silence from those who are trying to use this tragedy to attack Obama, Clinton, and Rice). Given that Stevens knew the situation in Benghazi as well as anybody, why did he decide to take the risk? It seems that he must have felt the risk was reasonable. Granted he wasn't as omniscient as those who now bleat that "we knew we were going to be attacked" (with their 20/20 hindsight), so it's probably Obama's fault that Stevens didn't have a perfect crystal ball.
One other finding, quoted from the
Washington Post article since I haven't had time to read the whole report yet:
"The committee described the attacks as opportunistic and said there was no specific warning that they were about to be carried out."
This is consistent with the CIA analysis, administration statements, and the New York Times investigation all stating that other protests about the anti-Islam video were one of the factors in the attack. That does not mean they "caused" the attack, but it could have triggered the timing.
