Argentina expressed frustration at the prosecutor's decision, describing it as unhelpful and saying it would not help release the hostages.
Milei told the Argentinian Jewish community that he was doing all he could to bring the perpetrators of the bombing to justice as part of his campaign.
Milei made the revelation while speaking Wednesday night at the Shul of Bal Harbor, a large Chabad synagogue in the Miami area.
Argentina’s government froze it’s initiative to move it’s embassy from Tel Aviv to Jerusalem in order to appoint Rabbi Axel Wahnish to be the new Argentinian ambassador to Israel.
Milei's visit to the Western Wall was one of the first things he did when he arrived in the Holy Land, bringing the leader to tears.
“Discrimination in Argentina is a problem suffered by various groups,” the country’s umbrella Jewish group said.
"The Office of the President thanks the Israeli Defense Forces, the Shabak and the Israeli Police for having successfully completed the rescue of the Argentines Fernando Simon Marman and Louis Har."
Milei, a maverick right-wing libertarian, in the past called Francis an "imbecile," a "son-of-a-bitch preaching communism" and the devil's man on earth.
Milei regularly studies Torah and has shown a close connection with the Chabad movement.
