Video from the briefing shows Psaki fielding questions from Playboy reporter Brian Karem as she donned a face mask and prepared to leave the White House briefing room after a gathering with a roomful of journalists.
"Hey Jen, will he take a physical anytime soon and report it to the American public?" Karem asked about Biden, who will turn 79 years old on Nov. 20 and is the most aged man ever to serve in the Oval Office.
"He will," Psaki responded.
"How soon? Do we know?" Karem asked.
"I don't have an update for you but will soon," Psaki responded.

"But before the end of the year?" Karem kept stressing.

"I promise you," Psaki answered. "Kelly [O'Donnell from NBC News] asks about this all the time. She's keeping us on our toes."
Psaki's interaction with Karem came two days after the press secretary had asked the question of a Biden physical check at a previous briefing.

"It is standard for every president to get a physical," Psaki said Tuesday. "He will get a physical too. When he gets physical, we will make all of that information available."
In September, O'Donnell also asked Psaki about Biden's health after the president was seen coughing during several public appearances.

"We've seen him on many occasions where he has a repeated cough. What is the situation with that cough and is that a concern?"
"I don't think it's an issue of concern," Psaki said Sept. 16. "There's a range of reasons why we need to clear our throat or have a light cold."

Psaki added that a doctor travels with Biden, and the president undergoes regular evaluations of his health.
Back in May, during previous issues about Biden's health, Psaki said that Biden was physically fit and healthy.
"I can tell you, having traveled with him a fair amount, sometimes he's hard to keep up with," said Psaki, who was 42 at the time and will turn 43 on Dec. 1.

New questions about Biden's health may have been prompted by the recent hospitalization of former President Bill Clinton. He was being administered in California for a urological infection and was assumed to leave the hospital Sunday, having been accepted last Tuesday after feeling fatigued.
Clinton, who turned 75 in August, is nearly four years younger than Biden.
