Clinton was invited to appear before the committee investigating the Sept. 11, 2012 terrorist attack earlier this week

Clinton's supporters argue that the House committee is trying to embarrass the former secretary of state as she runs for president

Boston CNN  — 

Hillary Clinton’s campaign said Saturday morning that she will publicly testify before the House Select Committee on Benghazi on Oct. 22. But a committee spokesman later said the former secretary of state’s lawyer was demanding limitations on the questioning, casting doubt over whether she’ll appear.

Clinton was invited to appear before the committee investigating the Sept. 11, 2012 terrorist attack earlier this week, and the former secretary of state and 2016 presidential candidate accepted that invitation on Friday, campaign spokesman Nick Merrill said.

Merrill said Clinton was “pleased” to receive the invitation to a public hearing from committee chairman Rep. Trey Gowdy. A Democratic Benghazi Commitee spokesperson told CNN that Gowdy offered several dates in October.

But Jamal Ware, the select committee’s communications director, disputed that a date had been set, saying that Clinton’s lawyer, David Kendall, was insisting that the scope of the questioning be limited to the Benghazi attack – and not other subjects, such as Libya and her use of a private email server, as Ware claims Kendall had previously agreed to – and that the hearing date would not change.

“The committee will not, now or ever, accept artificial limitations on its congressionally-directed jurisdiction or efforts to meet the responsibilities assigned to the committee by the House of Representatives,” Ware said in a statement. “Accordingly, once there is an agreement on the date and a better understanding of how, if at all, Secretary Clinton’s lawyer’s latest writing differs from previous ones, the committee will announce said hearing date.”

A message left with Clinton’s campaign regarding Ware’s statement was not immediately returned Saturday afternoon.

2016 shadow looms over hearing

The latest development on Clinton’s testimony comes after a protracted back and forth between the Republican-controlled committee and Clinton’s allies on Capitol Hill and in Washington. Republicans contend that the committee is solely interested in looking into the terrorist attack that killed four Americans – including Ambassador Christopher J. Stevens – while Clinton was secretary of state. Clinton’s supporters argue that Gowdy’s committee has become nothing more than a political arm of the Republican Party, looking to score points against Clinton ahead of the 2016 presidential campaign.

Clinton agreed to testify before the committee in May. Gowdy, however, rejected that offer and asked the secretary to appear twice – once on her exclusive use of a private email server while at State and another in regard to the Benghazi attack.

Kendall, who has spearheaded Clinton’s communication with the committee, said the former first lady would only testify once on both topics and offered to do it during the week of May 18 or later.

The date came and went, however, with no testimony.

When it became clear Clinton would have to testify before the committee, her allies and campaign aides had hoped that testimony would happen earlier rather than later in the hopes of not allowing Gowdy to drag the testimony into the heat of the 2016 contest. Clinton’s aides, however, have told reporters that they are confident the former senator would be able to hold her own in front of the committee.

The top Democrat on the committee, Rep. Elijah E. Cummings, accused Gowdy last week of overstepping the bounds of his committee.

“It appears that much of the Select Committee’s work has been shelved while Republicans pursue every possible avenue of political attack against Secretary Clinton,” Cummings said in a letter to Gowdy. “These actions by the Select Committee – which lack any legitimate basis – serve only to delay its work further into the election season and subject it to increasingly widespread criticism for its highly partisan actions.”

Gowdy has maintained, however, that he is only interested in getting to the bottom of the Benghazi attack and Republicans have complimented him for leaving politics out of it.

Clinton’s email gained renewed focus on Friday after the inspector general for the intelligence community has informed members of Congress that some material Hillary Clinton emailed from her private server contained classified information, but it was not identified that way when they were sent. Because it was not identified, it is unclear whether Clinton realized she was potentially compromising classified information.

The story emboldened Republicans on Friday to call for Clinton to turn over the private email server she used as secretary of state.

“The number of questions surrounding Secretary Clinton’s unusual email arrangement continues to grow,” Gowdy said in a statement on Friday. “The best – the only way – to resolve these important factual questions is for her to turn over her server to the proper authorities for independent forensic evaluation.”

Clinton turned over 55,000 pages of emails to the State Department earlier this year and the Benghazi committee is in the process of going through those messages.
