On Friday June 9, 2006, López Obrador promised to deliver documentation that would prove the allegations. Later that day, Claudia Sheinbaum from the López Obrador campaign arrived at Calderón campaign headquarters with three filing boxes. They were met outside by the vice-coordinator of Calderón's campaign, and by the press and a notary public who had been called by the Calderón campaign. The vice-coordinator of the campaign insisted that the boxes be opened and the contents catalogued and witnessed by the notary public before they were brought inside. A verbal confrontation ensued; during this confrontation, the boxes were opened and it was found that they were almost empty and contained only a handful of copies of documents the PRD had made public previously, and three CDs. Sheinbaum attempted to explain what the contents were, but a shouting and shoving match began among PAN and PRD members present. The accusations against Zavala were discontinued after the confrontation, though they were never withdrawn.
