The Secret Service said Friday that it has no record of having to prevent White House physician Rear Adm. Ronny Jackson from disturbing former President Barack Obama during a foreign travel mission in 2015.

“Over the last 48 hours, media outlets have alleged that U.S. Secret Service personnel were forced to intervene during a presidential foreign travel assignment in order to prevent disturbing (former) President Barack Obama,” the Secret Service said in a press statement Friday. “The Secret Service has no such record of any incident; specifically, any incident involving Rear Admiral Ronny Jackson.”

After a review of all internal documents related to presidential foreign travel in 2015 and conducting interviews with those who were present during those trips, the Secret Service concluded that the allegations of intervention hold no validity.

“Rear Admiral Jackson, in his role as the official White House Physician, has provided years of dedicated support to the men and women of the Secret Service, often miles from home and under difficult travel conditions, in order to ensure our personnel are healthy and prepared to execute our critical mission,” the Secret Service said in its statement.
