Biden: I’ll be more mindful of respecting personal space
DOVER, Del. -- Former Vice President Joe Biden acknowledged Wednesday that his tendency toward physical displays of affection and encouragement has made some women uncomfortable, and he promised to be "much more mindful" of respecting personal space. "Social norms have begun to change. They've shifted," the 76-year-old Biden said in a cellphone video posted to Twitter.
