In response, during a campaign stop in Graham's home state of South Carolina on Tuesday, Trump gave out the senator's cell phone number.

Within moments, Graham's voicemail was full.

On Wednesday morning, the New York Daily News trumped the presidential candidate's move and printed Donald Trump's phone number.

But on Wednesday morning's Fox and Friends, Trump was unapologetic and said: "I don't regret giving out the phone number.”

Republican presidential candidate Marco Rubio also joked about his competitor on Wednesday’s Fox and Friends.

“We already have a president who has no class. We don't need another one," he said.

Trump did get some support - at least from his own three children. They told People magazine, "Our father is a true visionary and a great mentor."
