President Obama's re-election campaign slammed presumptive GOP nominee Mitt Romney today, claiming he's trying to re-write history and take credit for the auto industry comeback, calling it "preposterous."

"This is a candidate who will literally say anything. Who thinks that his record and his statements don't matter," Obama campaign spokesman Ben LaBolt told reporters on a conference call this morning.

Ahead of a speech today in his native state of Michigan, Romney claimed he should be given credit for the resurgence of the auto industry.

"The auto companies needed to go through bankruptcy before government help, and frankly that's finally what the President did," Romney told ABC News' Cleveland affiliate WEWS on Monday. "He took them through bankruptcy. That was the right course I argued for from the very beginning… I pushed the idea of a managed bankruptcy, and finally when that was done and help was given, the companies got back on their feet, so I'll take a lot of credit for the fact that this industry's come back."

While the president pushed for the auto bailout in 2009, something he is eager to remind voters of, Romney wrote an op-ed saying the government should not provide funding for the auto industry and should instead "Let Detroit Go Bankrupt."

The president's campaign accused Romney of trying to erase his previous political position. "[Romney] thinks that he can reinvent himself in front of any new political audience that he's in front of with the magical power of the Etch-a-Sketch," LaBolt said.

"There have been a lot of unbelievable statements during this campaign from this candidate but this might be the most preposterous of them all," he said.
