Since returning to office last year, the president has repeatedly spoken about taking control of the Danish territory, arguing that the United States “needs” to own Greenland immediately for reasons tied to national security.

The proposal has drawn sharp criticism from European leaders. In response, Trump has threatened to impose a ten-percent tariff on eight European countries beginning in February. According to the administration, those tariffs would increase to 25 percent by June if negotiations fail to secure what Trump has described as the “complete and total purchase of Greenland.”

The escalating rhetoric has fueled public concern that a global conflict could erupt if the United States were to pursue military action in the region. As a result, some of Trump’s critics have suggested using the 25th Amendment as a means of removing him from office.
What is the 25th Amendment?

The amendment was drafted by federal lawmakers following the assassination of John F Kennedy in 1963, with the goal of clarifying presidential succession and incapacity.

Section 4 of the amendment allows for presidential authority to be temporarily transferred to the vice president without formally removing the president from office. While a sitting president could attempt to block such action, Congress ultimately holds the power to enforce the transfer through a two-thirds vote in both the Senate and the House of Representatives.Under this provision, the vice president — currently JD Vance — along with a majority of the 15-member Cabinet, must jointly declare that the president is unable to fulfill the duties of the office.
Although the amendment has never been used to remove a sitting president, it has been invoked on two occasions involving temporary transfers of authority to vice presidents.
