During World War II , Suckley often stayed for long visits at the White House , keeping the president company . Although Roosevelt is known to have had an affair with Lucy Mercer during World War I , there is no direct evidence that he had a similar relationship with Suckley , although there was an emotional connection . Roosevelt apparently instructed Suckley to burn at least some of the letters he wrote to her , which has fueled speculation about their content . Surviving letters include affectionate personal remarks , as well as reports and reflections about the progress of the war and meetings with figures such as Winston Churchill and Joseph Stalin at the Yalta Conference
