interested in a new liberal party which would be formed once peace came that would combine the left of the two existing major parties, but Willkie broke off contact with the White House after there were leaks of this to the press, because he felt that Roosevelt had used him for political gain. Roosevelt sent a letter expressing his regret for the leak, but that too was printed in the papers, and Willkie stated, "I've been lied to for the last time." In spite of their breach, Roosevelt continued to try to conciliate Willkie. Roosevelt's son Elliott later stated that his father hoped to have Willkie be the first Secretary General of the United Nations, and the two men agreed to meet later in the year. Willkie had not been invited to speak at the 1944 Republican National Convention in Chicago that nominated Dewey for president, and he declined a pass as an "honored guest". Dewey hoped to get Willkie's endorsement, and he sent his foreign policy advisor, John Foster Dulles, to see Willkie.

He went to New York by rail in mid-September, but on the trip he was stricken with another heart attack. Although his advisors told him to seek treatment and abandon the trip, Willkie pressed on. When he arrived in New York, Willkie was in great pain and his press secretary called an ambulance to take him to Lenox Hill Hospital. He recovered to some extent, enough so that his friends expected him to be discharged. He spent time working on the galleys of his second book, An American Program, and planned future projects. On October 4, Willkie caught a
