The chairman of the House Intelligence Committee said Sunday he believes "more whistleblowers" will come forward with information on the deadly attack last year on diplomatic outpost in Benghazi, Libya.

"I do think we are going to see more whistleblowers. I know certainly my committee has been contacted, I think other committees [have been contacted] as well," Rep. Mike Rogers (R-Mich.) said on "Fox News Sunday."

Rogers's comments came days after a trio of State Department officials criticized the Obama administration's actions regarding the Sept. 11, 2012 attacks at a House Oversight and Government Reform Committee hearing.
