Republican presidential bets Sen. Lindsey Graham of South Carolina and business magnate Donald Trump continued their feud, this time with Graham destroying several cell phones in various ways ostensibly to spite Trump who earlier publicly revealed his rival's mobile phone number.

Trump gave out Graham's cell phone number to the audience at a rally in South Carolina on Tuesday in response to Graham calling him a "jackass" a day earlier, according to Fox News.

Striking back, Graham on Wednesday uploaded a video on YouTube through IJ Review titled "How to destroy your cell phone with Sen. Lindsey Graham" where he is seen chopping a cell phone, putting one in a blender, smashing another with a bat and golf club, placing another phone inside an over toaster, burning one using a lighter fluid and smashing another phone with a block.

At the end, he says, "If all else fails, you can always give your number to the Donald. This is for all the veterans."

The video has been watched almost 840,000 times at the time of this writing.

The two Republican party mates have been at odds since Trump called Sen. John McCain "not a war hero."

McCain served during the Vietnam War while Trump avoided being drafted.

On CBS' "This Morning," Graham called Trump a "jackass" who is "slandering everybody and anybody to stay in the news. You know, run for president, but don't be the world's biggest jackass."

At the rally on Tuesday, Trump revealed to the crowd Graham's phone number.

"I don't know if it's the right number, let's try it ... so I don't know, it's three, four years ago so maybe it's an old number ... give it a shot," he said.

Trump attacked Graham on his poll ratings, saying that "I see your senator – what a stiff, Lindsey Graham, by the way, he's registered zero in the polls, and he's on television all the time."

A Fox News poll placed Trump with 18 percent while Graham had less than 1 percent.
