Fox News segment explodes when Meghan McCain takes Juan Williams to task over Obamacare's failures

A Fox News panel on "The Five" exploded late Thursday during a discussion about the decision of House Republicans to pass the American Health Care Act, which is the GOP plan to replace Obamacare.

The panel, with the exception of co-host Juan Williams, lauded congressional Republicans and President Donald Trump for the success of the AHCA.

But Williams called the legislation a "fraud" and suggested that his co-hosts have "mental illness" because of their perception of what the AHCA means for Americans.

Williams explained that passing the bill was a desperate attempt by the Trump administration to save face, given they had few accomplishments in the administration's first 100 days. As Williams continued to flesh out his point, his co-hosts Jesse Watters and Mehgan McCain began to interrupt him.

But when Williams refuted a point from Watters, who said that older people in Arizona are paying outrageous premiums thanks to Obamacare, McCain went off.

"Honestly, how dare you," she told Williams. "My own state has been hit the hardest by far."

Indeed, according to estimates, premiums in Arizona under Obamacare skyrocketed by as much as 116 percent this year, an increase much higher than the national average increase of 25 percent.

And McCain wasn't going to let Williams get away with denying that fact.

"I want Juan to go to Arizona and talk to people I know who are paying more than their mortgage for Obamacare premiums," she said. "It’s a disaster!"

"Why are you freaking out so much if nothing happened? If this isn’t a big deal, why are you freaking out?" McCain went on to exclaim.

"I'm telling you, this is a lie," Williams shot back.

"You’re freaking out!" McCain responded. "And Democrats are freaking out because we know it’s a victory!"

While McCain and Williams were going back and forth, producers panned to see the awkward expressions on the faces of Watters and co-host Kimberly Guilfoyle.

"Let me tell you something: Don’t mess with McCain," Guilfoyle said as she and co-host Greg Gutfeld ushered the panel to a commercial break.
