Tempers were raw between rival Republican presidential candidates Rudy Giuliani and Mitt Romney on Thursday after a lively debate that included what the Romney camp called a nasty attack by Giuliani.

The two candidates — Giuliani ahead in national polls and Romney leading in the two early voting states of Iowa and New Hampshire — went toe-to-toe on Wednesday on illegal immigration and other issues.

In the sharpest exchange of the night, Giuliani had a tough response when Romney insisted New York had been a sanctuary city for illegal immigrants when Giuliani was mayor.

Giuliani labeled the former Massachusetts governor’s home a “sanctuary mansion” and accused him of turning a blind eye to illegal immigrants working on its upkeep.
