Live Blog: The Second U.S. Presidential Debate

Question 8: Man in the audience asks next question, this time on Libya. Directs question to Obama asking about reports that U.S. staff involved in attack in Libya were denied extra security.

Obama says he called for investigation into exactly what happened around the attack, which killed Ambassador Christopher Stevens and three others. Obama says his stance was "we are going to find out who did this, and we are going to hunt them down."

Obama says he is ultimately responsible for what's taking place there.

Romney says he feels deeply sympathetic for the families of those who lost loved ones in the attack on the U.S. Consulate in Benghazi. He says the president rightly acknowledged that he is responsible for the failure to provide extra security.

Romney criticizes Obama for holding campaign events in the days after the Benghazi attack and the death of four Americans.

Romney characterizes Obama strategy as a "strategy of leading from behind."

Question 7: Woman in audience asks Romney what he would do about undocumented immigrants living in the U.S.

Romney says the country is a nation of immigrants and that "we welcome legal immigrants into this country." He says he wants the process to be streamlined.

Romney says he will not grant amnesty to people who have come here illegally.

Romney says the kids of those who came here illegally should have a pathway to become a permanent resident of the U.S., such as through military service.

Romney challenges Obama record on immigration, asking why Obama failed to pass an immigration bill during his first term.

Obama says the U.S. is a nation of immigrants. Obama says young people who have come here understand themselves as Americans and that the nation should make sure it gives them a pathway to citizenship. Obama says Romney said he would veto the DREAM Act that would allow these young people to have access. Obama says Romney encouraged self-deportation and called the Arizona law a "model for the nation."

Obama says Romney's charge that he did not try is not true.

Romney says he did not say that the Arizona law is a model for the nation but that the e-Verify portion allowing employers to determine whether a person is in the country illegally was a model for the nation.

Romney says his view is that Obama should have honored his promise to accomplish immigration reform in his first year in office.

Romney says he is not in favor of rounding up people and taking them out of this country, but of allowing them to choose.

Obama attempts to interrupt Romney as Romney begins to address issue of Chinese companies.
