ABC News' Matthew Jaffe reports: No sooner had he arrived in Denver for the Democratic convention, Sen. Barack Obama's, D-Ill., vice-presidential pick, Sen. Joe Biden, D-Del., threw down a stern warning to Sen. John McCain's, R-Ariz., presidential hopes.
"We're gonna give 'em the devil," Biden told supporters as he stopped for lunch at the Mile High City's Bodey's Smokehouse.
"That's right, you give 'em hell!" came the cry from a woman in the crowd of about 100 that quickly formed when they learned that the veep nominee would be coming to the downtown Writer Square BBQ spot for his midday meal.
Biden spent about five minutes shaking hands with the onlookers, who swarmed around him as soon as he arrived.
"I'm running with Obama," he said. "I'm running for Obama!" drawing cheers from the crowd.
Then the Delaware lawmaker headed over to the small Hickory Smoked Pit BBQ Express stand to order a handful of pulled pork sandwiches. "Keep five," he told the cashier as he gave a generous tip after paying for his food.
Dressed in a blue blazer and khakis on the hot late August day in Denver, Biden was accompanied by his wife Jill, son Beau, daughter Ashley, and brother Jim as they grabbed some grub.
Only hours before, Biden had touched down in Colorado after flying out this morning from his Wilmington home. Before leaving Delaware, he stopped off at the Amtrak station he uses every day to commute to Capitol Hill. There, he was given a warm welcome by home state supporters who sent him off for the start of a whirlwind few months on the campaign trail leading up to the November election.
On Monday night, Biden and his wife will attend Michelle Obama's speech at the convention. Two nights later, on Wednesday, Obama's running mate will take his turn at the mic and address his party as half of the ticket that Democrats hope will win the White House this fall.
