AUSTIN, Texas (AP) _ A former aide to Rep. Lloyd Doggett was sentenced to 30 days in jail after pleading guilty Tuesday to stealing $168,000 from the congressman's campaign.

Kristi Willis, 38, worked in Doggett's Austin office from 1998 to 2004, most recently as his district director.

She pleaded guilty to a count of felony misapplication of funds. She must serve four years' probation and pay $123,000 more in restitution. She already has returned $45,000 to the campaign.

Her attorney, Charles Grigson, earlier said that Willis had a spending addiction due to a psychological problem and that she was seeking professional help.

Doggett, a Democrat, has represented his Austin congressional district since 1995.
