DENVER (CNN) – Joe Biden hit the campaign trail Monday, flying solo for the first time since being named Barack Obama’s running mate and he vowed to run an aggressive campaign.
“You’re running with Obama?” an Obama supporter asked Biden during an appearance at a downtown Denver restaurant where he stopped for a photo-op.
“I'm running with Obama. I'm running for Obama,” Biden told the girl. "We're going to give them the devil."
Biden was accompanied by his wife, three children and his brother Jim as he gripped and grinned his way through the growing crowd.
Biden ignored most reporters’ questions, but when asked if he was surprised that Obama chose him for the number two spot, he responded simply, “I was pleased. I was pleased.”
The Delaware senator eventually made his way to the counter where he ordered five pulled pork sandwiches.
Biden will be in Denver throughout the convention. Tonight, he will attend Michelle Obama’s speech.
