Czolgosz's trial began in the state courthouse in Buffalo on September 23, 1901, nine days after McKinley died. Prosecution testimony took two days and consisted principally of the doctors who treated McKinley and various eyewitnesses to the shooting. Lewis and his co-counsel called no witnesses, which Lewis in his closing argument attributed to Czolgosz's refusal to cooperate with them. In his 27-minute address to the jury, Lewis took pains to praise McKinley. Scott Miller, author of "The President and the Assassin", notes that the closing argument was more calculated to defend the attorney's "place in the community, rather than an effort to spare his client the electric chair".
