Gov. Scott Walker (R-Wis.) was confronted on-air Wednesday evening by a group of progressive MSNBC hosts, including Rachel Maddow, Ed Schultz and Al Sharpton.

Speaking with NBC’s Ron Mott on the convention floor after Rep. Paul Ryan’s speech at the Republican National Convention in Tampa Bay, Fla., Walker said he was moved by a reference to a GM plant in Wisconsin that was closed despite President Barack Obama’s promise to the contrary.

“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,” said Ryan during his convention speech.

But then a group of MSNBC hosts jumped into the conversation, including Maddow, Schultz and Sharpton. Maddow questioned the veracity of Ryan and Walker’s claims, pointing out that the plant in question was closed in December 2008, before Obama took office.
