Donald Trump and Ralph Gilles are battling it out on Twitter over Mitt Romney's Jeep claims.

Mitt Romney's claim that Chrysler is shifting all Jeep production from the United States to China has sparked a war of words on Twitter between two rather unlikely combatants - billionaire Donald Trump and Ralph Gilles, Chrysler Group's vice president for product design.

The spat between Trump and Gilles started last Thursday when Trump took to the Twittersphere to chime in on Romney's statement that Jeep is planning to shift all production to China. Although Romeny's claim was totally off base, Trump used that false information as an opportunity to bash both President Obama and Chrysler via his personal Twitter account.

"Obama is a terrible negotiator. He bails out Chrysler and now Chrysler wants to send all Jeep manufacturing to China--and will!," Trump Tweeted.

Shortly thereafter, Gilles responded to Trump without mincing words. "You are full of (expletive)!," he wrote.

The battle continued on Friday with Trump Tweeting, "Looks like @RalphGilles is full of it. @dcexaminer: "Jeep, an Obama favorite, looks to shift production to China," referring to the title of an article published by the Washington Examiner last month.

Gilles responded once more, Tweeting: "@realDonaldTrump @dcexaminer as a business man you should understand the concept of localization. BTW We're expanding our Toledo Jeep plant!"
