A massive Chinese surveillance balloon that moved across the continental U.S. this week has been shot down.

• The Pentagon has confirmed the balloon was being used for surveillance, disputing China's claim that it was a civilian aircraft used for meteorological purposes.
• Brig. Gen. Pat Ryder said the balloon didn't pose a physical or military threat, and once it was detected, the U.S. took steps to protect against foreign intelligence collection of sensitive information.
• The FBI is expected to take custody of any recovered components of the balloon and ship them to its lab in Quantico, Virginia, for analysis and intelligence gathering, a senior government official told ABC News.
