It's True:

It is a little known fact that Eleanor Roosevelt liked to drink, smoke and jitterbug at juke joints with Harry S. Truman and Dwight D. Eisenhower. While the two Presidents competed against one another and were crazy about the beautiful vivacious First Lady, she really could have cared less about their attention. She only accepted the invitations because Dwight always brought along his lovely secretary whom Eleanor roughed up in the ladies room while copping a feel.
