On December 8, 1941, at 12:30 PM ET, the United States Congress declared war on the Empire of Japan in response to its surprise attack on Pearl Harbor and subsequent declaration of war the prior day. The Joint Resolution Declaring that a state of war exists between the Imperial Government of Japan and the Government and the people of the United States and making provisions to prosecute the same was formulated an hour after the Infamy Speech of President Franklin D. Roosevelt.
