In an interview for Post TV's "In Play", former House Speaker Newt Gingrich argued that President Obama's insistence that he would not negotiate with Congressional Republicans on raising the debt ceiling is "almost unconstitutional" and likened him to a king.

"This idea that suddenly 'Barack the First' announces to us, as the king, what he's going to do...Well that's not how the Constitution works," said Gingrich, who is now a host of CNN'S "Crossfire". " [Obama's] saying, 'Give me what I want, or else. Well he's not a king, and I think you have to really be careful. He could get sour very fast with the country, if the country concludes he's trying to be a petty dictator."

Gingrich added that past presidents -- including Ronald Reagan, Bill Clinton and George H.W. Bush -- all "put things on the debt ceiling".
