Franklin D. Roosevelt And Lucy Mercer
The alleged affair between Franklin D. Roosevelt and Lucy Mercer sparked more affairs for these two in the White House. She was working as the personal secretary of First Lady Eleanor at the time. Instead of getting a divorce, she grew tough and asked them never to see each other again. It is said that she later talked to Lorena Hickock when FDR was engaged in an affair with an assistant called Missy LeHand.
