U.S. President Donald Trump has once again stirred political debate after criticizing Chicago Mayor Brandon Johnson while reiterating his administration's position that Iran must never obtain a nuclear weapon.

In a statement shared on his Truth Social platform, Trump wrote that "someone should explain to the Pope that the Mayor of Chicago is useless, and that Iran cannot have a Nuclear Weapon." The remarks came after Mayor Johnson participated in a meeting with Pope Leo XIV at the Vatican as part of a multi-faith delegation.

The Chicago mayor had described his meeting with the Pope as one of the most inspiring and humbling experiences of his life, sharing photographs and details of the visit on social media. However, Trump's response quickly shifted attention from the Vatican meeting to his long-standing criticism of Johnson's leadership and his concerns about Iran's nuclear ambitions.

Trump has repeatedly argued that Iran should never be allowed to develop or acquire nuclear weapons, a position that has remained central to his foreign policy approach. His latest comments come amid heightened international discussions surrounding Iran's nuclear program and ongoing tensions in the Middle East.

The president's criticism of Mayor Johnson also reflects the continuing political divide over crime, governance, and public policy in major U.S. cities. Trump has frequently targeted Democratic-led cities, particularly Chicago, accusing local leaders of failing to address public safety concerns effectively.

The comments generated immediate reactions online, with supporters praising Trump's direct approach while critics argued that the statement unnecessarily mixed domestic politics with international diplomatic matters.

As debates continue over both America's relationship with Iran and the state of governance in major cities, Trump's latest remarks have once again placed him at the center of national and international political discussions.

Whether viewed as a foreign policy warning or a political attack on a Democratic mayor, the statement underscores Trump's willingness to combine global security issues with domestic political commentary as he continues to shape public discourse.
