Charles Krauthammer tonight said ISIS terrorists’ claim that a Jordanian airstrike killed American hostage Kayla Mueller is “preposterous.”

He said that nobody else in the building died, and there is no evidence that Mueller was even in the building. Mueller's parents today confirmed that their daughter has died while in the hands of the terror group.

“It obviously is a story concocted by congenital liars as well as killers to make it seem as if the Jordanians are responsible,” he said.

Krauthammer also weighed in on President Barack Obama’s reference to “vicious zealots” who “randomly shoot a bunch of folks in a deli in Paris.”

“I don’t understand why people define terrorism by randomness,” he said. “It is not.”

Krauthammer explained that the definition of a terror act is the use of violence to make a political statement. He said that all of these acts which appear to hit people randomly are backed by a religious ideology of the supremacy of Islam.
