A former John Edwards aide who was a key government witness against the 2008 Democratic presidential contender at his campaign finance trial has been arrested on charges of drunken driving and child abuse.

Court records show Andrew Young was arrested in Raleigh shortly before midnight Sunday and charged with impaired driving and misdemeanor child abuse. Young's 13-year-old son was with him, according to court records.

Young was released on a $2,000 secured bond.

In 2007, the married aide falsely claimed paternity of the baby Edwards fathered with a campaign videographer. Young testified at Edwards' 2012 trial that he took secret payments from two political donors to hide his boss' pregnant mistress.

Edwards was acquitted on one felony count, and the jury was unable to agree on a verdict on five other charges.
