It said that 40 percent believe Clinton used her personal storage device unethically but not illegally. Another 28 percent, it said, think Clinton broke the law.

An additional 27 percent believed Clinton did nothing wrong, while 5 percent had no opinion.

Thursday’s results come as the FBI is expanding its investigation into Clinton’s emails, according to Fox News.

Agents are probing her messages beyond a provision involving “gross negligence" with sensitive national intelligence, it said that morning.

They are now investigating whether statements Clinton or her aides made violate a federal statue on providing “materially false” information, the news outlet added.

Americans are also split over whether Clinton has adequately addressed her handling of the 2012 terrorist attacks on a U.S. diplomatic compound in Benghazi, Libya, the poll additionally found.

It discovered that 49 percent believe she has sufficiently answered questions about the incident.

Another 45 percent say that Republicans should keep investigating the matter, despite Clinton’s testimony before the House Select Committee on Benghazi late last month.

McClatchy-Marist conducted its latest survey of 1,465 adults via landline telephone from Oct. 29 to Nov. 4. It has a 2.6 percent margin of error.

Clinton has weathered months of scrutiny over her email arrangement at State since launching her 2016 presidential campaign last April. At issue is whether her server prevented accountability or exposed national security secrets during her tenure there.

Clinton leads the race for next year’s Democratic presidential nomination by nearly 22 points nationwide, according to the latest RealClearPolitics average of samplings.
