Pennsylvania Gov. Tom Corbett (R), says the NCAA badly overreached itself when it imposed punitive financial sanctions on Penn State over the handling of sexual predator and former Penn State assistant football coach, Jerry Sandusky.

In a statement early this morning, the Treasury Department says it's going to "exit" its investment in General Motors. The federal government holds just over 500 million shares of GM stock.

The automaker will buy 200 million of those shares, and the government will dispose of the rest "in an orderly fashion" over the next year and a half, depending on market conditions.

The issue of gun control appears to have moved into business and finance. One of the largest private equity companies in the country is terminating its relationship with a firearms corporation associated with one of the weapons used in the Newtown school shooting.

Update at 6:00 p.m. ET:

Michigan Gov. Rick Snyder has signed into law two controversial "right-to-work" bills passed earlier Tuesday by the state's House. This officially makes Michigan the 24th right-to-work state in the nation.

The two bills give both public and private employees so-called right-to-work protections — controversial pieces of legislation that have sparked protests in and around the state capitol in Lansing.
