The Republican Convention convened in Chicago from June 18 to 22. In the weeks leading up to the convention, many delegates remained uncommitted to a candidate, but by the time the convention formally opened, Taft had won the support of almost every unbound delegate. Roosevelt accused Taft of stealing votes and attempted to have delegates from Arizona, California, Texas, and Washington — all states supporting Taft — removed from the convention, but he was unsuccessful. The delegates chose Taft supporter Elihu Root to serve as chairman of the convention, a move that signaled that Taft was likely to win the nomination.
