Stephen Wigginton, a former U.S. Attorney for the Southern District of Illinois who joined Armstrong Teasdale two years ago, has pleaded guilty to driving under the influence of alcohol earlier this year.

A court in Madison County, Illinois, quietly dropped two other charges against Wigginton and ordered him to pay a $1,500 fine after accepting his guilty plea on July 11. The plea, to a Class A misdemeanor, was reported on Friday by local news sources.
