The letter noted that Mamdani co-founded a chapter of Students for Justice In Palestine at Bowdoin College when he was a student there, and it accused the group of praising Hamas' Oct. 7, 2023, attack in Israel.
"He has blamed the FBI for radicalizing al Qaeda terrorist Anwar al-Awlaki, undermining counterterrorism efforts. He has appeared alongside clerics who prayed for the annihilation of Israel’s supporters and praised Hamas fighters," the letter said.
The GOP lawmakers said granting Mamdani a security clearance could "empower agitators, escalate threats, and put more of these brave agents’ lives in danger."

He has pledged to be a mayor for all residents despite critics raising concerns about his hostile rhetoric toward Israel and lackluster pushback on questions of whether he supports Hamas.
Fox News Digital reached out to both Mamdani's transition team and the Department of Homeland Security (DHS) for comment.
