Live Blog: The Second U.S. Presidential Debate

Crowley follows up by asking whether it's in the purview of the government to bring gas prices down.

Obama says U.S. oil production has gone up and that the U.S. is using its resources more efficiently. Says natural gas isn't just appearing magically, but that the administration is encouraging it.

Obama criticizes Romney for once taking pride in shutting down a coal plant. Obama says the nation's oil imports are down to the lowest level in 20 years, oil production is up, natural gas production is up and the country is building cars that are more efficient.

Obama criticizes Romney for once taking pride in shutting down a coal plant. Obama says the nation's oil imports are down to the lowest level in 20 years, oil production is up, natural gas production is up and the country is building cars that are more efficient.

Romney charges that oil production on government land is down, Obama denies the charge, saying that's "not true."

Romney says he doesn't think anybody believes Obama is a person for gas, oil or coal, and says he will fight for them. The gas exchange gets tense with both candidates interrupting each other.

Romney says he will fight to create more energy in this country and to get America more energy secure. Says part of that is bringing in a pipeline from Canada.

Crowley asks Obama to address Romney's question about his own energy policy and its effect on gas prices.

Obama says Romney's policies will get country "back in that same mess."

Obama says he wants to create an economy that is strong.

Obama says he is all for pipelines and oil production, but not for ignoring other half of the equation, such as wind production.

Romney overrides moderator attempt to move on to next question.
