A husband was arrested for physically abusing his wife, and was subsequntly charged with aggravated battery. At the husband's criminal trial on the charges, the prosecutor called a doctor to the stand to testify. The doctor had provided the wife medical treatment several days after she had allegedly been battered by her husband. The doctor was to testify that, when the wife had come to his office for medical treatment, the doctor had asked her how she had sustained her injuries, and the wife had replied, My husband. He has a horrible temper and completely lost control. Is the doctor's testimony admissible?
