"D," the head of the Mossad's international relations branch, announced on Monday that he was stepping down from his position following the approval of Roman Gofman to head the Mossad, according to KAN News.
Other senior officials are expected to follow suit in the coming days, KAN added.
Gofman was cleared Monday to lead the agency after the High Court of Justice rejected petitions challenging his appointment.
Gofman's appointment faced intense legal hurdles, with two petitions filed against it. One was filed by Ori Elmakayes, a former IDF soldier who was 17 at the time of the events in 2022.
The Ori Elmakayes affair
The petitions centered on the Ori Elmakayes affair, which claimed that Elmakayes was used in 2022 by the IDF's 210th Division as part of an influence effort while Gofman commanded the division.
Elmakayes was later arrested over publications on his Telegram channel, held behind bars for 44 days, indicted, and eventually released to house arrest. The indictment against him was canceled in 2023 after his lawyers raised claims that he had been operated by the division - claims the attorney-general said later proved correct.
"Today, my struggle in the High Court of Justice against the appointment of Roman Gofman came to an end," Elmakayes wrote on Twitter/X on Monday. "Although the court chose not to intervene and to allow the appointment, I am at peace with the struggle and the many achievements it yielded."
Smotrich, Ben-Gvir, Bennett, others respond to Gofman's appointment
Finance Minister Bezalel Smotrich claimed that Attorney-General Gali Baharav-Miara had "led a campaign of defamation, humiliation, and demonization" against Gofman before his appointment.
"From the very first day, I knew that Roman Gofman was worthy of being head of the Mossad," Smotrich said in a Twitter/X post.
National Security Minister Itamar Ben-Gvir congratulated Gofman on Twitter/X, saying: "Roman is a fighter, a commander, and a true Zionist who knows Israel's security challenges both from the field and from the decision-making rooms. I wish him luck."
Defense Minister Israel Katz said echoed Ben-Gvir's sentiments on Monday, adding that he was glad the attempts to stop Gofman's appointment failed, and that "justice has prevailed."
"His success is our collective success," Katz said.
Former prime minister Naftali Bennett also wished Gofman luck in his new role, and thanked the outgoing chief, David Barnea, for his "dramatic tenure in service to Israel's security."
President Isaac Herzog, in his statement, recalled visiting Gofman in the hospital on October 8, 2023, after the IDF Maj.-Gen. was severely wounded in battle.
"That moment reflected Roman's courage of heart, his patriotism, and his profound [dedication to the] mission...I wish him and the Mossad great success."
