Democratic presidential candidate and former Secretary of State Hillary Rodham Clinton testifies on Capitol Hill in Washington, Thursday, Oct. 22, 2015, before the House Select Committee on Benghazi.

Washington ? A Republican member of the House Benghazi committee says he is “hopeful” that the Justice Department will bring charges against Democratic presidential candidate Hillary Clinton for having classified information on her private email server.

Rep. Mike Pompeo of Kansas says there is increasing evidence that “an enormous amount of information” on Clinton’s private server is classified.

“It was classified when it was on her server and it was classified when it was sent,” Pompeo told conservative radio host Lars Larson on Thursday.

House Benghazi Committee Chairman Rep. Trey Gowdy, R-S.C., center, with House Benghazi Committee members Rep. Mike Pompeo, R-Kansas, left, and Rep. Susan Brooks, R-Ind., speaks to the media on Capitol Hill in Washington, Wednesday, Jan. 6, 2016, after a closed-door hearing questioning former CIA Director David Petraeus in the investigation of the 2012 attacks on the U.S. consulate in Benghazi, Libya, where a violent mob killed four Americans, including Ambassador Christopher Stevens.

Pompeo said he is “anxious” for the Justice Department and FBI to make a determination on whether to bring charges against Clinton as quickly as possible. If charges are made, a grand jury would determine whether to indict.

“I think that there is only one answer that can be reached, and I am hopeful that will be the outcome that the FBI achieves,” Pompeo said.

“These are just facts,” Pompeo added. “We’ve all seen the reports of the classified information on her server. It could not and should not have been lawfully handled in the way that she did it.”

Pompeo’s comments came as the panel interviewed former Defense Secretary Leon Panetta behind closed doors on Friday. The remarks are the latest by a congressional Republican suggesting an unfavorable judgment against Clinton before the committee or the FBI concludes their respective investigations.

House Majority Leader Kevin McCarthy, R-Calif., said last fall that the Benghazi panel could take credit for Clinton’s recent drop in public opinion polls. He later retracted the comment.

Rep. Richard Hanna, R-N.Y., said “a big part” of the Benghazi investigation “was designed to go after … Hillary Clinton.”

Clinton was secretary of state at the time of the 2012 attacks in Benghazi, Libya.

Panetta had not testified before the Benghazi panel until now, but he told Congress in 2013 that time, distance and the lack of an adequate warning prevented a more immediate response to the Sept. 11 attacks that killed U.S. Ambassador Chris Stevens and three other Americans.

Panetta told MSNBC this week that “there was never any order to stand down. On the contrary, the whole effort was to do everything possible to try to save lives.”

The Republican staff on the committee issued a statement on Friday defending the panel’s work and criticizing Democratic members, underscoring how Benghazi remains a highly politically charged issue more than three years after the attacks.
