Giuliani and Santorum Join Attacks on Biden

WASHINGTON — Vice President Joseph R. Biden Jr. came in for an unapologetic drubbing on Sunday from two prominent Republicans for suggesting last week before a largely African-American audience that Mitt Romney's policies would unshackle Wall Street but put some Americans "in chains."

In turn, a spokeswoman for President Obama tried to turn the focus to language used by Mr. Romney himself.
