Former White House doctor for Bush, Obama, Trump says Biden must take cognitive test before debate

In an appearance on Fox News on Sunday, Jackson said Biden's health is a "national security issue" and emphasized the need for transparency regarding the President's physical condition leading up to the Thursday debate.

“I’m gonna be demanding on behalf of many millions of concerned Americans right now that he submit to a drug test before and after this debate, specifically looking for performance-enhancing drugs,” Jackson said on Fox News.

Jackson, who currently sits on the House Armed Services Committee, further asserted the importance of the issue for national security, emphasizing the necessity of having a head of state who can function daily without medication.

"We need a commander-in-chief, we need a head of state that can function on a day-to-day basis without being medicated, and that's why this drug test is important,” added Jackson.

Prior to holding office in Congress, Jackson served as the White House physician to the president from 2013 to 2018 under both Barack Obama and Donald Trump. Jackson’s calls for Biden to take a drug test echoes sentiments expressed by Trump, who has repeatedly suggested that Biden is being administered medical stimulants to aid his performance during speeches and public appearances.

“So, a little before debate time he gets a shot in the a*s and that’s — they want to strengthen him up. So, he comes out, he’ll come out — OK. I say he’ll come out all jacked up, right?” Trump said at a previous rally.

Biden is currently 81 years old. Should he win a second term in the White House, he would be 86 when he leaves office. This would far surpass the oldest president to ever leave office, which was Ronald Reagan who finished his second term at 77 years old.
