Hillary Clinton broke out in laughter Thursday evening when asked by Rep. Martha Roby (R-Ala.) if she was home alone on the night of the 2012 Benghazi attacks.

The bizarre reaction came as Clinton continued to testify into the evening before the House Select Committee on Benghazi.

"Were you alone?" Roby asked.

"I was alone, yes," Clinton replied.

"The whole night?" Roby followed up.

"Well, yes. The whole night," Clinton answered as she broke out into laughter.

Roby wasn't amused.

"I don't know why that's funny," she told Clinton. "I don't find it funny at all."
