The newspapers reported rumors about Japanese Americans being spies.
Explanation:
Newspapers recorded reports of fireballons, Japanese cars, and Japanese aircraft over the West Coast, as well as Japanese-Americans named Nisei and Issei becoming spies, in fear of an assault on the continental homeland. This contributed to the formation of a national protection army, as did most Americans who regarded the Issei and Nisei as spies and otherwise contributed to the US.
