At the Republican convention Paul Ryan blamed Obama for the closing of the Janesville, WI GM auto plant. Fact checkers pointed out that the official closing took place on Dec 23, 2008, before Obama took office. Today, George Will, claimed that the plant had continued to be open until April of 2009.
At the link, you can find a picture of the closing ceremonies on Dec 23, 2008.
In fact, a skeleton crew (57 workers) finished assembly of some vehicles until April of 2009 - and a few others continued to decommission the plant even after.
Sounds like another Ryan "two fifty something" marathon to me.
