December 8, 1941: U.S. Marine guards are stationed in front of the U.S. Capitol as President Franklin D. Roosevelt addresses a joint session of Congress one day after the attack on Pearl Harbor. Within an hour of the president’s address, Congress passed a formal declaration of war against Japan, and the United States officially entered World War II.

An earlier version of this cutline misidentified the guard stationed outside the Capitol. The guard is a U.S. Marine.
