Right-wing Michigan think tank, funded by Koch, Walmart and Blackwater families, now combing emails of three universities for mentions of Rachel Maddow

Talking Points Memo explained:

Mackinac Center, a Michigan think tank funded by big names in the conservative movement ranging from the Kochs to the Wal-Mart Waltons to the family that founded Blackwater, used the Freedom Of Information Act to request copies of every email sent or received by labor studies professors at state universities that mentioned Wisconsin, Gov. Scott Walker (R-WI), the city of Madison and Maddow. The universities have not decided how to respond, but the professors say the FOIAs suggest Mackinac is trying to catch them in illegal political advocacy. Mackinac has declined to speak on the record about the requests.
