At the China summit in May, President Donald Trump asked Chinese Communist Party Secretary General Xi Jinping to release prisoners of conscience pastor Ezra Jin and Jimmy Lai. The two heads of state are to meet again in September, in Washington, giving the president another shot at freeing Lai. Jimmy Lai shares important similarities with Jin. The notion that he lacks the power to pardon Lai is laughable — he himself consolidated these powers. President Trump should press Xi again to free Jimmy Lai.
