On December 21, government lawyers withdrew an appeal in Federal Court made by his predecessor, over the constitutionality of a memorandum she had signed with the Iranian government, to investigate the 1994 AMIA bombing. The memorandum was criticized by both Israel and Argentina's Jewish community, as Iran was long suspected of being involved in the attack. The memorandum had been ruled unconstitutional by a federal court during Kirchner's administration, and along with the withdrawal of the appeal, the memorandum was voided by Macri's administration. The move was praised by Israeli Prime Minister Benjamin Netanyahu as an improvement of bilateral relations.
