alisyn: we're back now with former defense secretary donald rum fed, the author of "known and unknown: a memoir." and we are talking about security concerns in libya ahead of the terror attack that killed four americans on 9/11. mr. secretary, you mentioned pram ma's trip -- president obama's trip to las vegas on september 12th. chief white house adviser david plouffe defended that decision this weekend, and he said that, basically, president obama is the president 24/7, he can multitask. what do you think of that? if you were secretary of defense today, what would you be advising the president to do about this benghazi situation? >> i think that the benghazi situation is a part of a pattern that we're seeing in the not just the arab world, but the islamic world. and it seems to me that the people in the white house including the president have a responsibility to the country to focus on what is apparently a very serious and broad, deep problem.
