Both GM and Chrysler are speaking out against Romney's latest ad campaign.

Following harsh comments from the United Auto Workers union, both Chrysler and General Motors are now speaking out against an "inaccurate" ad campaign from presidential hopeful Mitt Romney.

In an effort to win votes in the state of Ohio, Romney recently launched an ad campaign slamming President Obama for selling "Chrysler to Italians who are going to build Jeeps in China." The ad also takes shots at General Motors, claiming the company's growth in China is coming at the expense of jobs in the U.S.

However, both GM and Chrysler say Romney is incorrect on both accounts and are now asking to be left out of this year's campaign.

"This ad was so misleading, that we had no choice but to offer a vigorous defense of our progress since emerging from bankruptcy," Greg Martin, a GM spokesman, told Bloomberg. "We are grateful to both parties for the second chance, and we're making the most of it."

He added: "GM's creation of jobs in the U.S. and repatriating profits back to this country should be a source of bipartisan pride. GM has gone out of its way to be neutral."

Chrysler has also been fighting to set the record straight.

"Despite clear and accurate reporting, the take has given birth to a number of stories making readers believe that Chrysler plans to shift all Jeep production to China from North America, and therefore idle assembly lines and U.S. workforce," Gaulberto Ranieri, a senior vice president for corporate communications, wrote in an Oct. 25 blog on the Chrysler Web site. "It is a leap that would be difficult even for professional circus acrobats."

Romney is still standing behind his campaign ads, and that stance is unlikely to change with just days left before voting.
