A defiant Vice President Joe Biden is denouncing Republican criticism over his remarks to southern Virginia voters that presidential challenger Mitt Romney would put them "back in chains" but concedes he meant to use different words.
The campaign flap began after Biden told supporters in Danville, Va., that the Republican ticket wanted to "unchain Wall Street." He then added: "They're going to put y'all back in chains."
Biden, speaking later in Wytheville, says he had meant to use the term "unshackled."
But he did not apologize and mocked the Romney campaign for showing outrage.
