WASHINGTON (AP) - Ashley Biden, the only daughter of Vice President Joe Biden, is engaged to be married.
    
A spokeswoman for Jill Biden, the vice president's wife, confirmed the engagement Monday. Spokeswoman Courtney O'Donnell says the family is "thrilled" by the news.
    
Ashley Biden is a 30-year-old social worker. Her fiancé, Dr. Howard Krein, is a Philadelphia-based physician who specializes in ear, nose and throat and in facial and reconstructive surgery.
    
The couple became engaged in September after dating for about a year, and word began to leak after the vice president referred several times to his "future son-in-law" at an event in Wilmington, Del., on Friday.
    
Joe Biden also has two sons from his first marriage. His first wife and infant daughter were killed in a car accident in 1972.
