A top adviser to Mitt Romney is defending Rep. Paul Ryan's (R-Wis.) Wednesday convention speech against charges that it was misleading.

At issue is Ryan's remark blaming President Obama for the closure of GM plant in his home town. Ryan said: “Right there at that plant, candidate Obama said: ‘I believe that if our government is there to support you … this plant will be here for another hundred years.’ That’s what he said in 2008. Well, as it turned out, that plant didn’t last another year. It is locked up and empty to this day.” The plant was largely shut down before Obama took office.

"He didn't talk about Obama closing the plant. He said that candidate Obama went there in 2008, and what he said was 'With government assistance, we can keep this plant open for another 100 years.' Here we are four years into his administration. That plant is still closed," Romney adviser Eric Fehrnstrom said on CNN's "Starting Point" Thursday morning.
