President’s cold turns into grippe
Washington – (Dec. 31)
President Roosevelt was in bed with a slight case of grippe today following two days of confinement to his quarters with a head cold.
William D. Hassett, a White House secretary, told correspondents this morning:
I am sorry to inform you now that the President has the grippe. Dr. McIntire [Adm. Ross T. McIntire] reports he has about a half degree of temperature and that he has ordered him to stay in bed today, and probably will keep him in bed tomorrow.
As a result of the President’s illness, the Cabinet meeting, as well as the Friday morning press conference, was canceled.
