Physician to the president Kevin O'Connor declared in a memo to White House press secretary Karine Jean-Pierre that the president remains "fit for duty and fully executes all of his responsibilities without any exemptions or accommodations."

"This patient's current medical considerations are detailed as above, and remain stable and well-controlled. They include obstructive sleep apnea, a-fib with normal ventricular response, hyperlipidemia, gastroesophageal reflux, seasonal allergies, spinal arthritis and sensory peripheral neuropathy of the feet. For these, he takes three common prescription medications and three common over-the-counter medications," O'Connor noted.

"President Biden is a healthy, active, robust, 81-year-old male, who remains fit to successfully execute the duties of the Presidency, to include those as Chief Executive, Head of State and Commander in Chief," the physician added.

Jean-Pierre said during a press briefing on Wednesday that Biden's doctor and the neurologist do not think that the president needs a cognitive test.

Biden, who is the oldest president in U.S. history and would be 86 by the end of a second term in office, is currently seeking re-election and appears likely to easily lock up his party's presidential nomination.

He decisively won the Democratic presidential primary in Michigan on Tuesday while Democratic Rep. Dean Phillips of Minnesota, who has been attempting to challenge Biden for the nomination, performed dismally. According to results being reported by the Associated Press, more than 81% of the votes were for Biden while more than 13% were for the "uncommitted" option, and less than 3% went to Phillips.

The results being reported by the AP also indicate that Phillips received fewer votes than Marianne Williamson, who announced that she was suspending her campaign earlier this month. But Williamson announced on Wednesday that she was "unsuspending" her campaign.

"Dem primary voters and Party people don't wish to entertain alternatives to Joe Biden - and I honor that. But that doesn't change the fact Donald Trump is walking right back to the Presidency while we sleepwalk from it. I've dedicated 8 years of my life resisting that dangerous man, and it remains my singular mission to ensure his defeat at the ballot box in November," Phillips tweeted. "I'm not going anywhere and not suspending my mission. I will continue to assess the most proficient approach to protecting America, Americans, and our treasured democracy," he added.
