The Best Moments From The Second Democratic Debate

National security and Wall Street were major topics of conversation.

Just three candidates participated in the second Democratic presidential primary debate Saturday night.

CBS News hosted the debate at Drake University in Des Moines, Iowa.

The candidates included former Secretary of State Hillary Clinton, Sen. Bernie Sanders (I-Vt.) and former Maryland Gov. Martin O'Malley.

With the deadly attacks in Paris taking place only a day before, the debate put major focus on national security, gun control and regulating Wall Street.
