The second inauguration of Calvin Coolidge took place on March 4, 1925 marking the beginning of his second term as the thirtieth president of the United States. Chief Justice and former president William H. Taft administered the Oath of office. It was the first time an inauguration was broadcast nationally on radio.Soon after his election, Vice President-elect Charles G. Dawes sent an insulting letter to President Coolidge informing him that he would not be attending cabinet meetings, and thus having angered the President, he then proceeded to publicly attack the entire U.S. Senate.
