Republican presidential candidate and real estate mogul Donald Trump gave out his rival candidate Sen. Lindsey Graham’s (R-SC) cell phone number on Tuesday during a speech in Bluffton, South Carolina.

Trump told the crowd that Graham had previously been “begging” for a mention on the Fox News show “Fox & Friends” when the real estate mogul still made regular weekly appearances.

“I wrote the number down! I don’t know if it’s the right number, but let’s try it,” Trump said, proceeding to read the 10-digit phone number.

Trump said it was an old number so it might not be work. He then repeated the number.

Politico reported that it called Graham at that number after Trump gave it out and the senator picked up.

“When it comes to the Donald, nothing surprises me anymore,” Graham told Politico on Tuesday. “It’s just too bad, really.”

This isn’t the first time Trump has doxxed someone who he believes wronged him. When Univision anchor Jorge Ramos sent a handwritten request for an interview, with his personal cell phone number, Trump published it on Instagram. It’s since been deleted.

When the number is called, a recorded message says the mailbox is full.

Probably getting a new phone. iPhone or Android? — Lindsey Graham (@LindseyGrahamSC) July 21, 2015
