Former Vice President Joe Biden is joking about the controversy about unwelcome contact with several women. Speaking at a labor union conference in DC today, Biden said -- "I just wanted to let you know I had permission to hug Lonnie." That was a reference to a union executive at the conference. He later invited several children on stage and put his arm around a young boy, saying -- "He gave me permission to touch him." In a Twitter video statement this week, Biden vowed to be more "mindful and respectful of people's personal space."
