The problem is not one congressman asked “Do you think this is funny?”
Roby pretty much called her on her laughter:
ROBY: Secretary Clinton, I want to follow up on the questions about the night of the attack and decisions made then. You wrote in your book,”Hard Choices,” that you were directing the State Department response the night of September 11th, 2012, but you also stated that you left your office on the night of the attack and went to your home in northwest Washington because you said you knew the next few days were going to be taxing and the department was going to be looking to you.
I want to talk about a few things. Do you have a skiff (ph) in your home?
CLINTON: Yes, I did.
ROBY: OK. And who else was at your home? Were you alone?
CLINTON: I was alone, yes.
ROBY: The whole night?
CLINTON: Yes, the whole night.
(LAUGHTER)
ROBY: I don’t know why that’s funny. I mean, did you have any in-person briefings? I don’t find it funny at all.
CLINTON: I’m sorry — a little note of levity at 7:15, noted for the record.
ROBY: Well, I mean, the reason I say it’s not funny is because it well into the night when our folks on the ground were still in danger. So I don’t think it’s funny to ask you if you were alone the whole night.
CLINTON: Well, Congresswoman, you asked if I had a skiff. I had secure phones. I had other equipment that kept me in touch with the State Department at all times. I did not sleep all night. I was very much focused on what we were doing.
By the way, here’s the video of the exchange - it was playing, but not well for me ..... you can still get the full effect of Hilly’s amusement at Roby’s question.
