The fallout from Mitt Romney’s misleading Jeep ad continued Thursday, with real estate mogul Donald Trump chiming in on Twitter and a Chrysler executive responding, telling Trump he is “full of shit.”

The automaker has been rebuffing the false suggestions made by the Republican presidential nominee last week in Ohio, and in misleading campaign ads, that Jeep would move U.S. production to China. Chrysler has already issued a strongly-worded denial.

However, on Tuesday, Trump continued the lie by tweeting, “Obama is a terrible negotiator. He bails out Chrysler and now Chrysler wants to send all Jeep manufacturing to China--and will!”

Less than an hour after Trump’s tweet was out, Gilles, who heads product design for Chrysler, lashed out at the mogul’s claims with five words that went viral.

@realDonaldTrump you are full of shit!” Gilles wrote -- and was promptly retweeted more than 3,000 times.

Gilles did apologize for his language, but did not delete the tweet.

“I apologize for my language, but lies are just that, lies,” Gilles’ second tweet read.

Jeep is a global brand of the Chrysler group, and the carmaker, owned by Italy's Fiat (Milan: F)  is looking to restart halted production in China -- but not, Chrysler pointed out earlier this week, to move American jobs there.

Ohio is considered one of the key swing states in next week’s general election. Though President Barack Obama has continued to maintain a narrow lead in the Buckeye State, both campaigns are putting up a strong fight there. No Republican has won the presidency without winning  Ohio.
