A special Congressional panel is carrying out an investigation into the terror attacks on the US consulate in Benghazi, Libya. Four Americans were killed in the incident that took place in 2012.

Former US Secretary of State Hillary Clinton’s lawyer said Hilary would testify before the panel. Clinton's lawyer David Kendall stated in a letter to lawmakers that Clinton would testify for one time in the week of May 18 or later.

“The secretary is fully prepared to stay for the duration of the committee's questions on the day she appears”, said Kendall.

House Representative Trey Gowdy, chairman of the US House Select Committee on Events Surrounding the 2012 Terrorist Attacks in Benghazi, requested that Clinton should testify twice. He asked Clinton to testify at a hearing on the Benghazi attacks and second on her use of private emails during her tenure as secretary of state.

But her lawyer said she would testify once. At that time, Hillary would answer all the questions by the committee. In May 2014, House Speaker John Boehner created the House special panel, so that the investigation can be carried out into the Benghazi attacks.

In the attacks, the US Ambassador to Libya Christopher Stevens and three other Americans were killed. Clinton had to face a lot of criticism for mismanagement and also, to conceal information with regard to the attacks. In January 2013, Hillary has already testified at a Congressional hearing on the Benghazi attacks and at that time, she was attending the office.

In that hearing, she defended herself. Now, when Hillary is contesting presidential seat in 2016 elections, Republicans do not want to leave an opportunity to show that Clinton's time at the State Department was a situation in which she lacked competence and leadership.
