Several potential Democratic presidential candidates for 2028 gathered at a convention in New York to criticize President Trump's recent statements regarding Iran. The event focused on opposition to what speakers characterized as aggressive rhetoric from the current administration.

Former Secretary of State John Kerry delivered some of the sharpest criticism during an appearance on MSNBC's "The Briefing" with Jen Psaki on Friday. Kerry specifically referenced Trump's recent posts on Truth Social, describing them as sounding like a "prelude to becoming one of the greatest war criminals in history."

Kerry's comments addressed multiple Trump posts, including what was described as an expletive-laden message posted on Sunday and a threatening statement made on Tuesday. The former secretary of state's remarks represented some of the most direct language used by Democratic leaders in response to the president's Iran-related communications.

The New York gathering brought together Democrats who are reportedly considering presidential bids, with Iran policy emerging as a central theme of criticism against the Trump administration. Attendees framed their opposition around concerns about what they termed military escalation.

The convention highlighted growing Democratic unity around foreign policy criticism of Trump, particularly regarding Middle East strategy and diplomatic approaches to Iran.
