Argentine presidential candidate testifies as witness in case against Cristina Kirchner Argentina's center-left opposition presidential candidate, Alberto Fernandez, speaks to press after testifying as a witness in a court case investigating his running mate, former president Cristina Kirchner, for allegedly covering up alleged Iranian involvement in an attack in 1994. The summons to Fernandez is based on an interview he gave in February 2015 in which he harshly questioned Kirchner for signing a pact with Iran, which was never applied, which sought to interrogate Iranian officials, accused of an attack on the Jewish mutual AMIA in Buenos Aires in July 1994 killing 85 people, outside of Argentina.
