Is Trump mentally fit? asks Nikki Haley on comparison with Nancy Pelosi

Republican presidential candidate Nikki Haley on Saturday during one of her election rallies, raised questions on former US president Donald Trump’s, "mental fitness", CNN reported. 

"The concern I have is, I'm not saying anything derogatory, but when you’re dealing with the pressures of a presidency, we can't have someone else that we question whether they're mentally fit to do it," she was quoted as saying.

Her comments come after Donald Trump at a campaign rally confused her with former white house speaker Nancy Pelosi when talking about the January 6, 2021, US Capitol attack.

In response, Trump boasted about his cognitive ability saying, "A few months ago I took a cognitive test … and I aced it."

In an interview with Fox News, Haley said: "We need people at the top of their game, I'm not saying that this is a Joe Biden situation, but I'm saying, are we going to go and have two eighty-year-olds running for president?"

She further went on to suggest that candidates running for the presidency above the age of 75 should be mandated to take mental competency tests.

Nikki Haley and Donald Trump are both running for the presidency in the 2024 US election from the republican side. 

In the first Republican Election faceoff in Iowa, Trump came in first winning 20 seats out of 40 followed by Ron DeSantis and Nikki Haley.
