"I deeply regret any offense my remark in the New York Observer might have caused anyone. That was not my intent and I expressed that to Senator Obama," Biden said in a statement today.

Biden explained that he did not intend the comment to be derogative towards former African American Presidential contenders, such as Rev. Jesse Jackson and Al Sharpton, but rather as indicative of Obama's charisma.

Obama, according to Biden, "is probably the most exciting candidate the Democratic or Republican parties have produced since I've been around. He's fresh, new, smart, insightful. Lightning in a jar."
