Using Toulmin's model of argument as its methodology, this paper analyzes the arguments employed by Lee Iacocca, chief executive officer of Chrysler Corporation, to persuade the United States Congress to provide backing for loans necessary for the corporation's financial survival in 1979-1980. After delineating the three main claims made by Iacocca (the government should help Chrysler, the government should provide loan guarantees for the corporation, and the government should guarantee such loans) and the data used to back those claims (federal regulations caused Chrysler's problems, the corporation was the major employer for thousands of workers, and the government had previously guaranteed loans to other corporations), the paper employs W. Brockriede and D. Ehninger's methodolgy to show how Iacocca advanced his argument by means of rhetorical lines of proof. The paper then examines the communication strategies Iacocca used before the House Committee on Banking, Finance, and Urban Affairs to assure the loan guarantees, concentrating on the claims, data, and warrants of his three major arguments. The final section of the paper looks at the perceived effect of Iacocca's strategies, showing how his ability to press his argument contributed to the survival of Chrysler Corporation. The paper includes 11 references. (FL)
