In an interview Tuesday night, NBC News' Cynthia McFadden asked Hillary Clinton whether she is willing to testify before the House Select Committee on the Benghazi attack. Clinton said "we'll see," adding she doesn't want to "prejudge it."

The former secretary of state also noted that the hearings may not be "on the level," saying she doesn't want to be part of something that "politicizes or demeans the sacrifice" of the four Americans who died on Sept. 11, 2012.

Clinton said she kept a lot of notes - published in her new book - during the time of the Benghazi attack, prompting McFadden to ask whether she'd turn those over to Rep. Trey Gowdy's (R-SC) committee.

"They can read it in the book," said Clinton.

Bill Hemmer got some reaction to the new comments from Michael Ingmire, the uncle of State Department diplomat Sean Smith, who was killed in Benghazi. Ingmire does not believe Clinton is taking the issue seriously.

"She's an abject failure in a lot of ways. Her arrogance belies the seriousness of the matter of Benghazi," he said, adding he believes Clinton "is in love with the sound of her own voice."

Ingmire said it's "time to stop playing games" and Gowdy must subpoena Clinton for documents and to testify. He admitted he's not sure whether that would even bring the truth of Benghazi to light.

"I think Hillary Clinton is a serial liar to be honest with you. Her entire career has been based on a consistent amount of lying and hiding the truth. I think we're going to see the heart of darkness revealed in this case," said Ingmire.
