A political phrase referring to calls and discussions to invoke Section 4 of the Twenty-fifth Amendment to the U.S. Constitution to declare President Donald Trump unable to discharge the duties of his office, often cited in response to perceived erratic behavior or instability.

Notably revived in April 2026 following President Trump's profanity-laced Easter Sunday social media post threatening to bomb civilian infrastructure in Iran, prompting lawmakers like Rep. Lofgren to question his fitness for office.

Historically associated with multiple instances during Trump's presidencies, including post-January 6, 2021, but the amendment itself outlines procedures for presidential disability and succession.
