After his failure to get close enough on September 5, Czolgosz waited until the next day at the Temple of Music on the exposition grounds, where the president was to meet the public. Czolgosz concealed his gun in a handkerchief and, when he reached the head of the line, shot McKinley twice in the abdomen at close range.[205]
McKinley urged his aides to break the news gently to Ida, and to call off the mob that had set upon Czolgosz, a request that may have saved his assassin's life.[206] McKinley was taken to the exposition aid station, where the doctor was unable to locate the second bullet. Although a primitive X-ray machine was being exhibited on the exposition grounds, it was not used. McKinley was taken to the home of John G. Milburn, president of the Pan-American Exposition Company.[207]
In the days after the shooting, McKinley appeared to improve and doctors issued increasingly optimistic bulletins. Members of the Cabinet, who had rushed to Buffalo on hearing the news, dispersed, and Vice President Roosevelt departed on a camping trip to the Adirondacks.
