A panel of experts appeared on Fox News Tuesday evening to discuss the Affordable Care Act and the GOP’s proposed bill, and ex-Clinton advisor Simon Rosenberg went off the rails when things were not going his way.

When Melissa Francis asked Rosenberg what he would do to make the health care plan better, instead of answering he said he “rejects the entire framing of this conversation.”

He then raised his voice when the other panelists tried to chime in and Francis pressed him on her question. “I’m not answering your question,” Rosenberg exclaimed.
