Did John McCain adopt Carol Shepp McCain's children from her previous marriage?

Short answer...Yes, John McCain divorced his first wife. He evidently cheated on her numerous times after he came home from Vietnam. She had been in a horrible car accident while he was in Vietnam and was disfigured. He filed for a divorce after he met his current wife who was a much younger (17 years) lass and heiress to the 3rd largest Anheiser-Busch distributor in the US.
