In 1919, Lansing became the nominal head of the US Commission to the Paris Peace Conference. Because he did not regard the League of Nations as essential to the peace treaty, Lansing began to fall out of favor with Wilson, for whom participation in the League of Nations was a primary goal. During Wilson's stroke and illness, Lansing called the cabinet together for consultations on several occasions. In addition, he was the first cabinet member to suggest that Vice President Thomas R. Marshall assume the powers of the presidency. Edith Wilson was displeased by Lansing's independence, and requested Lansing's resignation in 1920.
