We're back, and now, on to Iran...
To Paul, you want to remove sanctions on Iran, which is trying to gain a nuclear weapon, supposedly.
The congressman says there is no credible evidence. Says he is afraid of "another Iraq" war from a president who "overreacts."

Now, to Santorum: Iran has trained jihadists; is that act of war? He says country has been acting war-like to US. Draws big applause.
