From 1943-45, Drury worked as the United States Senate correspondent for United Press which, as he wrote, gave him the opportunity "to be of some slight assistance in making my fellow countrymen better acquainted with their Congress and particularly their Senate." He worked as a reporter, but also kept a journal in which he recorded the events of Congress as well as his impressions and views of individual senators and the Senate itself. Drury's journal followed the career of Harry S. Truman from junior senator to President of the United States, and also covered "President Franklin D. Roosevelt and his contentious relations with the Senate." The journal was published in 1963 as "A Senate Journal 1943-45" after Drury had experienced great success with his 1959 novel "Advise and Consent".
