It was assumed that Marshall would become the Supreme Commander of Operation Overlord, but Roosevelt selected Eisenhower as Supreme Commander. While Marshall enjoyed considerable success in working with Congress and Roosevelt, he refused to lobby for the position. President Roosevelt didn't want to lose his presence in the States. He told Marshall, "I didn't feel I could sleep at ease if you were out of Washington." When rumors circulated that the top job would go to Marshall, many critics viewed the potential transfer as a demotion for Marshall, since he would leave his position as Chief of Staff of the Army and lose his seat on the Combined Chiefs of Staff.
