COLUMBIA, S.C. (AP) - The director of South Carolina's transportation department is resigning after a drunken driving arrest.
Robert St. Onge resigned Friday, citing personal reasons. Gov. Nikki Haley notified legislative leaders in a letter obtained by The Associated Press that Christy Hall will be acting secretary until she finds a permanent replacement.
Highway Patrol Sgt. Bob Beres says St. Onge was stopped about 8 a.m. Friday on Interstate 20. Beres says a breath test at the Lexington County jail registered his blood-alcohol level at 0.20 percent, more than twice the legal threshold.
The sheriff's department says St. Onge was released from jail Friday afternoon on his own recognizance.
Haley named the retired Army major general to lead the transportation department in January 2011.
No one answered the phone Friday at his home.Copyright 2014 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
