The Associated Press reported earlier this month that career lawyers were involved, but Lynch's comments are the most expansive to Congress.
"If the FBI makes the case that Hillary Clinton mishandled classified information and put America's security at risk, will you prosecute the case?" Republican Congressman John Carter asked Lynch during a budget hearing.
"Do you know of any efforts underway to undermine the FBI's investigation? And please look the American people in the eye and tell us what your position is as you are the chief prosecutor of the United States," Carter pressed.
Lynch replied, "...that matter is being handled by career independent law enforcement agents, FBI agents as well as the career independent attorneys in the Department of Justice. They follow the evidence, they look at the law and they'll make a recommendation to me when the time is appropriate."
