Democratic Presidential Candidate Hillary Clinton will answer questions Thursday from a Republican-led House committee investigating the 2012 Benghazi attacks.

The attacks led to the death of four Americans, like U.S. Ambassador to Libya Chris Stevens.

Hilary Clinton will face a grueling 8-hour grilling before the house committee investigating the 2012 Benghazi attacks, testimony that could prove pivotal for her presidential campaign.

"Can she weather a full days' worth of testimony in front of a committee that even some Republicans have said is aiming to hurt her politically. If she can do that she will be on stable ground after what was a pretty shaky summer," said John Dickerson.

The Republican-led committee will try to find out why the U.S. chose to remain in Benghazi despite the escalation in violence, Rep. Trey Gowdy said, "what I want to know is - while violence was going up in Libya why was our security profile going down

Clinton will also face questions from lawmakers on whether she was aware of requests for additional security at the consulate where the attacks took place.

Clinton, who was Secretary of State at the time, has already gone on the defensive during two previous testimonies.

"The fact is we had four dead Americans," Clinton said, "was it because of a protest or was it because of guys out for a walk one night who decided they wanted to go kill some Americans. What difference does it make?

Ahead of today's hearing, Democrats on the Benghazi committee released the transcript of the closed-door testimony of former Clinton Aide Cheryl Mills.

Mills testified that Clinton was devastated by the events and very engaged in her response.

Hillary Clinton is also expected to be asked about her *private* email server and the emails she sent the night of the Benghazi Attack.

This committee is the eighth major investigation into the attacks.
