Video is here, McCain's question begins ~1 hr 43 min mark. Here's transcript courtesy WSJ.com, slightly edited by me:
McCAIN: Four months after the Benghazi tragedy its a tragedy when we lose four brave Americans there are many questions that are unanswered. And the answers, frankly, that youve given this morning are not satisfactory to me. Were you and the president made aware of the classified cable from Chris Stevens that said that the United States consulate in Benghazi could not survive a sustained assault? Numerous warnings, including personally to me, about the security were unanswered or unaddressed.
It took a CNN reporter looking through the consulate to find Chris Stevens last warning. When were you made aware of that cable? When were you made aware of the attack on the British ambassador and the assassination attempts and the closing of the consulates there, and what actions were taken? What was the presidents activities during that seven-hour period?
On the anniversary of the worst attack in American history, September 11th, we didnt have Department of Defense forces available for seven hours. Two brave Americans died in the last hour. With all these warnings, all these things took place, we didnt have a single Department of Defense asset apparently available to come to these rescue.
You knew Chris Stevens very well. I knew him very well. I knew him on July 7th, when I went to Libya to observe the elections. And at that time, on July 7th, he expressed to me his deep and grave concerns about security, particularly in Benghazi. And he continued to communicate with the State Department, and I dont know who else was privy to those cables of his deep concern about the security there and the need for additional assistance. And I will argue with facts that after that event took place, after the fall of Gadhafi, the, quote, soft footprint was partially, to some degree, responsible for the tragedy that took place. The American people and the families of these four brave Americans still have not gotten the answers that they deserve. I hope that they will get them.
