Call for a cognitive test for Biden or withdrawal from the election race..

The discussion about the age of US President Joe Biden and his fitness to run in the upcoming election continues, a year before the American elections kick off.

On his part, Republican Representative from Texas Ronny Jackson, a former White House doctor, said that Biden's age and cognitive decline are two valid reasons for concern.

He added in an interview with the American "Fox News" network: "Biden's decline is happening quickly. As I said, I have cared for three presidents, so I know firsthand what it takes to be the commander-in-chief and head of state. It is a mentally and physically exhausting task, this man cannot do it."

Jackson served as a doctor under the administrations of George Bush, Barack Obama, and Donald Trump, and he has previously sounded the alarm about Biden's cognitive sharpness, even calling for him to undergo a cognitive test or withdraw from the 2024 election race.
