An American father and son accused of helping former Nissan Motor Co. Chairman Carlos Ghosn flee trial have asked U.S. Secretary of State Antony Blinken to halt their impending extradition to Japan.

On Saturday, the U.S. Supreme Court denied an emergency request by lawyers for U.S. Army Special Forces veteran Michael Taylor and his son, Peter Taylor, to pause a lower court order that cleared the way for them to be extradited.

A Feb. 3 letter to Blinken from the Taylors' lawyers, seen by Reuters on Wednesday, said "we do not believe there is any good reason to surrender these two American citizens."
