In November 1918, Florence's kidney swelled to ten times its regular size. This was perhaps her worst attack since 1905 and left her bedridden for weeks. She was treated by Dr. Sawyer's son Carl, who had been stationed at Camp Meade (now Fort Meade). Warren stayed at her side until it was clear she was feeling better. By March 1919 Florence had recovered enough to attend events at Evalyn's house while her husband golfed. Florence was in attendance at the Senate on July 10 when President Wilson requested America join the League of Nations, an idea she opposed. During the summer, her husband began to be mentioned as a potential presidential candidate, which Florence was initially not happy with since she thought he didn't have enough of a national reputation.
