US first lady says Joe Biden will never take mental competency test

US President Joe Biden will not undergo a mental competency test, and the idea to make politicians aged over 75 take it is “ridiculous”, First Lady Jill Biden said.

In February, former US ambassador to the United Nations Nikki Haley announced her candidacy for the 2024 presidential election. In her first speech as a presidential candidate, Haley proposed a mandatory competency test for politicians aged over 75, which was considered as a jab at Biden and former president Donald Trump, Haley’s competitor in the Republican primaries.
