By Nicolás Misculin BUENOS AIRES, Feb 26 (Reuters) - There is no evidence that President Cristina Fernandez tried to whitewash Iran's purported involvement in a deadly 1994 bombing, an Argentine judge told Reuters in an interview on Thursday after dismissing the case. On the contrary, the evidence suggested "the government exhausted all possibilities to enable the investigation into the AMIA (Jewish community center) attack to advance," said Judge Daniel Rafecas, who showed Reuters copies of the evidence.
