One of Gov. Robert F. McDonnell’s 21-year-old twin sons was arrested Saturday and charged with public intoxication, according to court records.

Sean McDonnell, who will be a senior this fall at the University of Virginia, was arrested at 1:19 a.m. after an officer observed him walking in the 1400 block of Wertland Street, an area with bars and restaurants not far from campus, said Lt. Ronnie Roberts, spokesman for Charlotesville Police Department.

McDonnell was charged with misdemeanor public swearing/intoxication, but Roberts said that is simply how the public intoxication charge is listed in the code. The officer did not report that Sean McDonnell was swearing, Roberts said.

Sean McDonnell was taken into custody, transported to a regional jail, and released on his own recognizance, the court records show. He is due to appear in Charlottesville General District Court on Aug. 12.

“This is a personal matter and is being addressed by the family,” McDonnell spokesman Tucker Martin said.

The arrest, first reported by the Richmond Times-Dispatch, comes on top of other troubles for the McDonnell family, as state and federal investigators probe gifts to the governor and first lady Maureen McDonnell. It came just one day after the governor reimbursed the state nearly $2,400 for food and other household items that Sean, twin brother Bobby and sister Rachel had taken from the mansion for use in their college dorm rooms.
