On Friday, hours before the scheduled Oath of Office ceremony in the Legislative Palace, the legislature erupted in a brawl. The incident was broadcast on live television. In spite of such events the ceremony took place. Calderón entered the Congress chamber through a back door directly onto the podium, and in a quick ceremony took the Oath of Office. Then, rather than deliver his inaugural address to Congress (the traditional follow-up to the oath taking), he left through the back immediately after the National Anthem was sung, and delivered the address in the National Auditorium, filled with supporters.
