Biden's power will be transferred to Vice President Harris while he undergoes colonoscopy

President Biden is getting his routine annual physical at Walter Reed Medical Center Friday, White House press secretary Jen Psaki said. Since the president's checkup will include a colonoscopy under anesthesia, power will be briefly transferred to Vice President Kamala Harris. 

"As was the case when President George W. Bush had the same procedure in 2002 and 2007, and following the process set out in the Constitution, President Biden will transfer power to the Vice President for the brief period of time when he is under anesthesia," Psaki said. "The Vice President will work from her office in the West Wing during this time."

The president signed letters addressed to congressional leadership informing them of the temporary transfer of power.
