Chotiner was quietly designated an alternate delegate to the convention as an original alternate had dropped out, and when Governor Warren learned of his selection, he "erupted ... furiously". Chotiner had volunteered to take care of many of the convention arrangements for the California delegation, and for the Warren campaign headquarters at the Conrad Hilton Hotel. Seeking to avoid a split with Nixon, who assured Warren that Chotiner was merely there to handle physical arrangements, the governor grudgingly allowed Chotiner to retain his roles. When the California delegation's train arrived in Chicago, the Warren campaign found that the buses which Chotiner had arranged to transport the delegation to its hotel were covered with "Eisenhower for President" banners—which the governor's supporters hastily replaced with Warren signs. Chotiner had an extra phone surreptitiously installed in the Warren headquarters so he could quietly communicate the latest developments to Nixon. He also remained in close contact with Eisenhower aide and future Attorney General, Herbert Brownell. Warren paid a courtesy call on Eisenhower, and later wrote in his memoirs, "Imagine my surprise when the doorkeeper who admitted me to the general's suite was Murray Chotiner." Eisenhower was nominated over Taft and Warren in a close, first-ballot victory. As a final indignity to Warren, it developed that Chotiner had overspent his budget, forcing the governor and others to pay hotel expenses from their own pockets.
