‘Ridiculous’: Jill Biden suggests Joe will never take competency test

​First lady Jill Biden on Sunday said it was “ridiculous’’ to consider GOP presidential hopeful Nikki Haley’s call to mandate mental competency tests for pols over 75, suggesting President Biden would never take one.

​Jill Biden said she and ​her husband — who at age 80 is the oldest commander in chief in US history and would be 82 at his inauguration if reelected — would “never even discuss something like that.

“Ridiculous,” Jill Biden responded when asked about Haley’s idea in a snippet of an interview that aired Sunday on CNN’s “State of the Union.” 

Jill Biden — whose full interview will air at ​9 p.m. Monday — pointed to the president’s surprise trip last month to Ukraine to meet with President Volodymyr Zelensky to mark the one-year anniversary of Russia’s invasion as proof of the commander-in-chief’s stamina.

“How many 30-year-olds could travel to Poland, get on the train? Go nine more hours, go to Ukraine, meet with President  Zelensky?” she said. “So, look at the man. Look what he’s doing. Look what he continues to do each and every day.”​
