President Joe Biden has called for new protocols and safeguards to protect against foreign espionage and surveillance in response to the U.S. military shooting down a Chinese spy balloon off the coast of South Carolina. The search for two other unidentified objects shot down near Alaska and the Great Lakes region have concluded with no sign of debris. The Navy, Coast Guard and FBI have collected all of the balloon's debris, which could reveal what information it was able to monitor and collect.
