Republican presidential candidate Donald Trump reportedly read rival GOP candidate Lindsey Graham's cell phone number during a speech in the South Carolina senator's home state.
After Graham called Trump a "jackass" on Monday for insulting Sen. John McCain's war record, Trump appeared at an event in Bluffton on Tuesday and almost immediately told the crowd that their senator was a "stiff" and an "idiot."
"Maybe the whole world has that number already," Trump spokesperson Michael Cohen later explained to CNN. "He is certainly their representative and they have every right to reach out to him."
