President Donald Trump’s letter to Norwegian Prime Minister Jonas Gahr Støre about acquiring Greenland has sparked pushback from his critics, bringing renewed attention to the 25th Amendment and how a president could be removed without impeachment.

Lawmakers, political figures, and more are calling for the 25th Amendment to be invoked after President Trump threatened to escalate the war in Iran.

President Donald Trump said he was “optimistic” about a deal with Iran but later threatened Tehran over charging fees in the Strait of Hormuz, as Israeli strikes in Lebanon and the continued closure of the vital waterway jeopardized diplomatic talks.

Some Republicans publicly broke with Trump over his threat that a "whole civilization will die tonight" if Iran does not reopen the Strait of Hormuz.
