You can watch the House Oversight Committee's hearings on the Libya embassy attack on C-Span here.
Short take: The more they talk, the more the story evaporates. Ambassador Kennedy is striving to make it sound like the now-retracted claim of a mob gathering prior to the attack wasn't so much a lie as a myth, or something. The best you can say is that the State Department's attitude toward protecting its assets was pretty, eh, laid back — a quality I wouldn't generally attribute to Secretary Hillary Clinton.
Lowest point so far: Rep. Jim Cooper (D-Tennessee) bogarts the mic and tries to take pressure off President Obama by reading a list of Americans killed abroad during the Reagan administration. At least they're not blaming Bush this time.
