Benghazi Testimony LIVE: Bob Casey Thanks Clinton For Service at Benghazi Hearing

Senator Bob Casey (D-Penn.) opens his question time by thanking Clinton for her service and mentioning three specific areas that she's worked hard to make a difference on:

1. Reducing the flow of calcium nitrate from Pakistan into Afghanistan, which finds its way into roadside bombs.

2. Work on behalf of women and girls around the world, particularly in Afghanistan.

3. Work on humanitarian assistance.
