The parents of two of the four Americans who died in the Benghazi attack in 2012 filed a lawsuit Monday against Democratic presidential nominee Hillary Clinton, alleging her "reckless handling" of classified information contributed to their deaths.

The case was filed in the U.S. District Court for the District of Columbia by Larry Klayman of Freedom Watch USA on behalf of Patricia Smith, the mother of Sean Smith, and Charles Woods, the father of Tyrone Woods, for allegedly wrongfully causing the death of their sons as well as for defamation and intentional and negligent infliction of emotional distress.

The lawsuit suggests that Clinton's use of a private email server contributed to the deaths of Smith and Woods, adding that terrorists were able to "obtain the whereabouts of Ambassador Christopher Stevens and thus the U.S. State Department and covert and other government operations in Benghazi, Libya and subsequently orchestrate, plan, and execute the now infamous September 11, 2012 attack."

"Having used a secret private email server that we now know was used to communicate with Ambassador Christopher Stevens with confidential and classified government information, and which we also now know was likely hacked by hostile adversaries such as Iran, Russia, China and North Korea aligning with terrorist groups, it is clear that Hillary Clinton allegedly negligently and recklessly gave up the classified location of the plaintiffs' sons, resulting in a deadly terrorist attack that took their lives,” Klayman said in a statement announcing the suit.

In addition to the wrongful death and negligence charges named in the suit, the parents also claim that Clinton defamed them in statements to the media, according to court documents.

"During her campaign for President, Defendant Clinton has negligently, recklessly, and/or maliciously defamed Plaintiffs by either directly calling them liars, or by strongly implying that they are liars, in order to protect and enhance her public image and intimidate and emotionally harm and silence them to not speak up about the Benghazi attack on at least four separate occasions," Klayman wrote in his complaint.

Patricia Smith has previously spoken out against Clinton, most recently at the Republican National Convention in July.

Clinton’s campaign pushed back Tuesday on the latest allegations.

"While no one can imagine the pain of the families of the brave Americans we lost at Benghazi, there have been nine different investigations into this attack and none found any evidence whatsoever of any wrongdoing on the part of Hillary Clinton,” spokesman Nick Merrill said in a statement.

In an interview last week on "Fox News Sunday," Clinton denied telling family members of those killed that the attack was sparked by an anti-Islam video, and was not terrorism.

She instead suggested the family members misunderstood her because they were overwhelmed by grief.

“I understand the grief and the incredible sense of loss that can motivate that,” Clinton said. “As other members of families who’ve lost loved ones have said, that's not what they heard. I don't hold any ill feeling for someone who, in that moment, may not fully recall everything that was or wasn't said.”
