BLUFFTON, S.C.—Republican presidential candidate Donald Trump has pulled a classic adolescent prank on a rival who dared to criticize him, a bit of payback reminiscent of writing the phone number of a nemesis on a wall with the message “Call me.”
After Sen. Lindsey Graham called Trump “the world’s biggest jackass” during a television interview, the billionaire developer read Graham’s personal cellphone number and showed it to TV cameras at a campaign event. Graham joked that he would have to buy a new phone. His voice mail quickly filled up.
