Biden's brother hospitalized after suspicious package powder scare

OCEAN RIDGE, Fla. -- The brother of Vice President Joe Biden says he was kept overnight at a Florida hospital after opening a suspicious package containing a powdery substance.

The envelope was mailed to Francis Biden's Ocean Ridge home. Biden told The Palm Beach Post that his girlfriend retrieved the package from his mailbox Saturday afternoon, but that he opened it.

Biden says white powder spilled from the envelope onto his skin. He says he immediately called authorities, who evacuated neighbors and closed the street.

Biden and his girlfriend were taken to a hospital. The woman was released Saturday, and Biden was released Sunday morning.

Biden says he's fine. He referred further questions about the powder and the envelope to the FBI.

The FBI has said the powder appears to be harmless.
