ABC News’ Z. Byron Wolf reports from Wilmington, Delaware: Sen. Joe Biden, D-Del., left his Wilmington house this morning before 8am with nary a word to reporters camped out in his driveway. Members of the news media have been staking out Biden’s home for two days as speculation swirls that Biden is on Democratic Sen. Barack Obama’s short list of vice presidential candidates. Biden is spending time in his home state while Congress is in summer recess. As the senator drove off this morning in his pickup truck it was unclear where his primary destination was. However, when he pulled back into his driveway at 9:15am he had made a pit stop at the local Brew Ha Ha Espresso Cafe and Newsstand and Cafe. As he rolled into his driveway he stopped his pickup and, without saying anything more than, "Hi" and "Nice talking to you," to waiting reporters, he handed a brew box of coffee and a dozen bagels out the window. All the reporters and camera people had their video cameras trained on him, so there was a moment where no one understood he was giving the bagels to us. One reporter was so flustered that he asked if Biden had talked to "Senator O’Biden." Tightlipped, Biden drove down his driveway. Journalists, ever thankless, soon realized that he brought cream cheese for the bagels and cream and sugar for the coffee. But no cups, which is just as well since there are no public restrooms within over a mile of his house. For the latest veepstakes coverage click HERE, HERE and HERE.
