Video: 'President Roosevelt addresses the Congress during a joint session after the Yalta...HD Stock Footage'

(Thursday, March 1, 1945, 12:08 p.m. EWT; during World War II) — In what turned out to be his final public speech, U.S. President Franklin D. Roosevelt laid responsibility for future world peace squarely in the lap of the Senate today in a historic appeal to a special joint session of Congress for full assumption by the United States of its responsibilities in “keeping the peace.”

Roosevelt delivered the speech while seated, publicly acknowledging his disability for the first and only time: “I hope that you will pardon me for this unusual posture of sitting down…but I know that you will realize that it makes it a lot easier for me not to have to carry about ten pounds of steel around the bottom of my legs.”
