Wal-Mart Director Quits -- After the Market Closes on a Friday, Of Course

A Wal-Mart bigwig is out of work after an internal probe shows evidence of "financial improprieties" of up to a half million bucks.

Thomas M. Coughlin quit after the probe turned up $100,000 to $500,000 in misused assets.

The SEC has filed a report in the case -- but it fails to detail specifics about what role -- if any -- Mr Coughlin played in the case. (ABC)
