President Donald Trump has removed Vice President JD Vance from a leading role in upcoming Iran negotiations, opting instead to rely on advisers including Steve Witkoff and Jared Kushner, a shift that comes amid escalating criticism of the administration's rhetoric and renewed calls for constitutional action in Washington.

The decision follows days of heightened scrutiny over Trump's statements regarding Iran, which critics have described as destabilizing at a moment of active conflict. Lawmakers from both parties have raised concerns about leadership and decision-making, with some urging consideration of the 25th Amendment to the United States Constitution.

Trump sought to minimize the significance of Vance's exclusion, citing "questions of safety and security" as the reason for the change. The explanation has done little to quell speculation that the move reflects internal disagreements within the administration over the direction of U.S. policy toward Iran.

According to accounts from individuals familiar with internal discussions, Vance had expressed reservations about escalating military engagement, warning that a broader campaign could carry significant regional and human costs. Those concerns placed him at odds with a more aggressive posture that has defined recent U.S. actions.

At the same time, Vance's position appears to have evolved as the likelihood of military action increased. In internal deliberations, he is reported to have argued for decisive force if conflict became unavoidable, underscoring the competing pressures facing senior officials during a rapidly shifting crisis.

The reshuffling of the negotiation team has drawn attention not only for its foreign policy implications but also for what it signals about decision-making dynamics inside the White House. Analysts say sidelining a vice president in high-level diplomacy is unusual and may reflect a desire to consolidate messaging authority during a volatile period.

The development coincides with mounting political backlash on Capitol Hill. More than 80 Democratic lawmakers have publicly called for action in response to Trump's rhetoric, with some arguing that existing legislative tools are insufficient. Representative Melanie Stansbury and others have framed the issue as a constitutional test, emphasizing the need for oversight.

The broader debate has centered on the limits of executive authority during wartime. Critics argue that Congress must reassert its role in authorizing and overseeing military engagement, while supporters of the administration maintain that rapid decision-making is essential in a high-risk geopolitical environment.
