Some Democrats have suggested invoking the 25th Amendment after renewed controversy surrounding President Donald Trump’s statements about annexing Greenland.

Since returning to office, Trump has argued the U.S. “needs” Greenland for national security and has threatened tariffs on European countries if Denmark refuses to negotiate.

His comments have unsettled European leaders and drawn criticism at home, with opponents warning that aggressive pressure could spark an international crisis.

These concerns have led some Democrats to publicly question whether Trump is fit to continue serving as president.

The 25th Amendment allows the vice president and a majority of the Cabinet to declare a president unable to carry out official duties, temporarily transferring power.

If a president contests the move, Congress can uphold it with a two-thirds vote in both chambers.

While the amendment has never been used to remove a president, it has been invoked before for temporary transfers of authority.

Lawmakers such as Representative Maxine Waters and Senator Ed Markey have urged consideration of the measure, reflecting rising political tension over Trump’s leadership and foreign policy direction.
