From COMM 455 student Jon Rittenberg:

Former chief usher at the White House Ike Hoover (left) wrote one of the earliest memoirs of life in the White House, and he mentions JW with some detail: “Until the time of Harding, all the presidents, so far as I know, wrote their own speeches. With his coming a man was appointed to prepare whatever set and formal speeches he was called upon to make. The first man to hold this office was Judson Welliver, a widely known newspaper man. He had been with the president through the campaign, being close to the throne, so to speak, an naturally came along to the White House. No doubt he had made himself useful along this very line during the campaign and it was most natural that he should kept on. When Coolidge came, he found Welliver on the job and continued to employ him., no doubt finding him a very handy man…As the whole scheme was a new one, there were many embarrassments for the individual holding down this job. For example, there was no legal appropriation for his salary. It was skimmed from here, there, and everywhere. At one time it was taken from the fund for the payment of the chauffeurs and the upkeep of the garage. Much jealousy was also aroused by this office. The regular secretaries seemed to resent the fact that, owing to the confidential nature of the work, the man holding this job had an entrée to the president which they themselves did not enjoy. He seemed always to be a separate part of the Executive Offices, under orders of no one but the president.”
