Did Abigail accuse Elizabeth of witchcraft?

Abigail accuses Elizabeth Proctor of witchcraft, most likely because she is married to John Proctor. Abigail had an affair with John and is in love with him. Accusing Elizabeth of witchcraft may get her out of the picture and make room for Abigail. A second reason for accusing her of witchcraft includes protection. If John's own wife is accused he will be less inclined to condemn all the girls, which would also now include his wife.
