Kris Paronto, one of the heroes of Benghazi, is furious with Barack Obama over the former president's recent remark about "conspiracy theories" surrounding the 2012 terror attack.

Speaking in Illinois on Friday, Obama said the politics of "division and resentment and paranoia" has found a home in the Republican Party, arguing that Republicans have embraced "wild conspiracy theories, like those surrounding Benghazi, or my birth certificate."

On "Fox & Friends First" on Tuesday, Paronto slammed Obama for being dismissive of the 2012 terror attack on a U.S. diplomatic compound in Benghazi, Libya, which left four Americans dead.

"To hear Obama say that, it's just another slap in the face," Paronto said. "It makes all of us tremendously angry, because he's trying to rewrite history and say that Benghazi didn't happen."

He said this just reinforces how important it is for Benghazi survivors and the family members of victims to speak the truth about what happened on September 11, 2012, and in the attack's aftermath.

Paronto was one of the security contractors who fought to repel terrorists from the besieged American diplomatic compound.

"You had Hillary Clinton say, 'What difference does it make?' That was hurtful, that was hurtful to the families. And now you've got Barack Obama calling it a 'conspiracy,'" Paronto said, saying it is "disgraceful and sickening" that they refuse to honor the families of Christopher Stevens, Sean Smith, Tyrone Woods and Glen Doherty.

He added that Obama and Clinton have failed to take responsibility for their failures before, during and after the attack.

"But then you remember the courage and the sacrifice of especially my teammates -- Tyrone Woods and Glen Doherty -- who gave everything," Paronto said. "So, you try to find the positives of it, the positives of the great American spirit and the positives of patriotism, of service members giving of themselves so others may live."
