Haley, 51, threw her name into the hat as a Republican presidential candidate last month and made headlines after calling for "mental competency tests."
NIKKI HALEY CALLS FOR POLITICIANS OVER 75 TO FACE ‘MENTAL COMPETENCY TESTS’
President Biden turned 80 in November and former President Trump, also a candidate for president this go-round, is 76.
A Fox News Poll conducted in late February found that, overall, 77% of Americans favor requiring such tests, with 83% of millennials, 84% of GenXers and 66% of Baby Boomers supporting the idea.

The study also found that 87% of Republicans, 74% of Independents and 67% of Democrats surveyed favor the mental capacity tests, as well.
PENCE DISAGREES WITH HALEY ON COMPETENCY TESTS: ‘AMERICAN PEOPLE CAN SORT THAT OUT’
Still, the First Lady rejected the idea of the tests when interviewed by CNN.
"How many 30-year-olds could travel to Poland, get on the train? Go nine more hours, go to Ukraine, meet with President (Volodymyr) Zelensky?" she asked the news network. "So, look at the man. Look at what he’s doing. Look at what he continues to do each and every day."
The First Lady is not the first to reject Haley’s proposal, and likely will not be the last.
In fact, former Vice President Mike Pence disagreed with the presidential hopeful’s proposal in an interview with CBS last week.
"I come from southern Indiana, where people think most politicians should have a competency test," Pence, 63, joked. "No, I think the American people can sort that out. I really do."
