In their own words

Vice President Joe Biden: "We will find and bring to justice the men who did this [in Libya]. ... Whatever mistakes were made will not be made again."

Rep. Paul Ryan: "If we're hit by terrorists, we're going to call it for what it is: a terrorist attack. ... What we're watching on our TV screens is the unraveling of the Obama foreign policy."

Ryan: "We've had four different sanctions, the U.N. on Iran, three from the Bush administration, one here. And the only reason we got it is because Russia watered it down and prevented the -- the sanctions from hitting the central bank.

... They're racing towards a nuclear weapon."

Biden: "These are the most crippling of sanctions in the history of sanctions, period. ... We will not let them acquire a nuclear weapon, period."

Ryan: "Romney's a good man. He cares about 100 percent of America."

Biden: "Stop talking about how you care about people. Show me something. Show me a policy."

Ryan: "There aren't enough rich people and small businesses to tax to pay for all their spending."

Biden: "We are leaving in 2014. Period. And in the process, we're going to be saving over the next 10 years another $800 billion."

Ryan: "We don't want to broadcast to our enemies: Put a date on your calendar. Wait us out."

Biden: "Instead of signing pledges to Grover Norquist not to ask the wealthiest among us to contribute to bring back the middle class, they should be signing a pledge saying to the middle class we're going to level the playing field."

Ryan: "Look, did they come in and inherit a tough situation? Absolutely. But we're going in the wrong direction."
