Underestimate Obama at 'own peril,' says GOP Gov. Chris Christie

Republican New Jersey Gov. Chris Christie criticized President Obama's leadership prowess and governing abilities, but warned detractors that if they underestimate the president's political savvy it would be at their "own peril."

"Those who underestimate the Barack Obama underestimate him at their own peril. He is as good a politician as I've ever seen," said Christie on OWN's "Oprah's Next Chapter."

Christie laid the responsibility of ending deadlock in Congress squarely at the feet of the president. He blamed Obama for what he called Congress's "war with itself" in the one-hour show with Oprah Winfrey, which airs Sunday, Jan. 15 on OWN.

"I think the only person who can call a truce on Congress's war with itself is the president," he said.

The New Jersey governor touted his own political leadership and willingness to work with Democrats in his state.

"There is a boulevard between getting everything you want and compromising your principles. I won't compromise my principles, but I acknowledge I won't get everything I want and I think that's what's not happening in Washington right now, and I think the only person who can make that happen right now is the president," Christie said.

Christie, who resisted pressure to run for the White House himself, announced his endorsement of GOP presidential candidate Mitt Romney in October.

As for Oprah, she has been open about her support of the president, appearing on the campaign trail for the then-Illinois senator in 2008.

Oprah called herself a "100 percent supporter” of Obama during an interview with CNN Friday, although she declined to officially endorse his reelection effort.

"If he or his office called me tomorrow and said that they needed me I would do whatever I thought would be of service," Oprah said.
