During the Eisenhower administration he had been asked many times to take on a role in government. He resisted that saying that” the president needed a friend” however he did lead an industry effort to look at the reorganization of the government's housing and mortgage finance systems. The recommendations in part, lead to the consolidation of a number of separate activities into the Department of Housing and Urban Development.
