To give his “Infamy” speech on the day after Pearl Harbor, Franklin Roosevelt rode to the Capitol in a car owned by Al Capone.

The Secret Service was concerned about assassination attempts, and Roosevelt’s regular state car had no protective features. So the president made use of Capone’s heavily armored 1928 Cadillac 341A Town Sedan, which the Treasury Department had impounded after the gangster’s arrest.
