In Michigan and Ohio, the Obama campaign will air a new ad going after Mitt Romney for his recent claims about Chrysler and General Motors, and reminding voters that Romney said he would let Detroit's automobile industry go bankrupt.
"We know the truth, Mitt," a voice-over says in the ad, titled "Cynical."
The Romney campaign has stood behind its statements and TV ads that strongly imply Chrysler moved production of Jeeps to China under President Barack Obama's watch. It's not true, and plenty of fact-checkers have pointed that out.
The Obama campaign quotes those fact-checkers in its new ad. More scathing, though, are the quotes from the CEO of Chrysler and a spokesman from GM, both of whom responded to the Romney ad earlier this week.
"GM calls Romney's ads 'politics at its cynical worst,'" the voice-over says. "And Chrysler's CEO said it's simply not true."
A Romney campaign adviser, who spoke on condition of anonymity, told HuffPost's Jon Ward on Wednesday that Romney's claims are accurate because the jobs that Chrysler added in China can be considered jobs that it did not add in the U.S.
In fact, Chrysler also added jobs in the U.S.
Watch the Obama ad.
UPDATE: 1:55 p.m. -- Amanda Henneberg, a spokeswoman for Romney, released the following statement in response to Obama's ad:
"President Obama can't run from the facts. As a result of his handling of the auto bailout, American taxpayers stand to lose $25 billion and GM and Chrysler are expanding their production overseas. Unlike President Obama, Mitt Romney has a comprehensive plan to revive manufacturing, create millions of good-paying jobs, and deliver real change and a real recovery."
