Liar, liar, pantsuit on fire: Hillary Clinton still insists she didn’t tell the grieving families of the Benghazi victims that an anti-Islam video was to blame.

Yet family members say she said just that, three days after the attack, at the Sept. 14, 2012, ceremony at Andrews Air Force Base.

George Stephanopoulos asked her Sunday if she’d told the victims it was about the film. Clinton gave a flat “no.”

She added: “I said very clearly there had been a terrorist group, uh, that had taken responsibility on Facebook, um . . .”

At least four family members disagree.

Tyrone Woods’ father said he hugged Clinton and shook her hand. Then “she said we are going to have the filmmaker arrested who was responsible for the death of my son . . . She said ‘the filmmaker who was responsible for the death of your son.’ ”

Sean Smith’s mother said Hillary is “absolutely lying . . . She said it was because of the video.” Smith’s uncle backs her up.

Glen Doherty’s sister agreed: “When I think back now to that day and what she knew, it shows me a lot about her character that she would choose in that moment to basically perpetuate what she knew was untrue.”

“What she knew” refers to Clinton’s words to daughter Chelsea the night of the assault and the next day to Egypt’s prime minister, which made it plain the secretary of state knew full well that a terror group had long planned the attack.

The lie’s even in her words at the Sept. 14 ceremony: “We’ve seen rage and violence directed at American embassies over an awful Internet video that we had nothing to do with.”

Just why the administration united around this lie is another editorial. The disgrace here is Clinton’s refusal to admit her role — even pushing the fib to “comfort” the bereaved.

Stiff as the competition is, this has to count as her lowest-down, dirtiest lie of all.
