MIAMI (AFP) - The younger brother of US Vice President Joe Biden spent the night in hospital after opening a package from India that contained white powder initially feared to be anthrax, reports said Sunday. Francis Biden, 57, told local media in southern Florida that his girlfriend Mindy had retrieved a large Manila envelope addressed to him from their roadside mailbox in Ocean Ridge at about noon on Saturday. "She retrieved it, but I was the one who opened it," Biden said, quoted by The Palm Beach Post. "It was mailed from India."
