What evidence do mary warren and john proctor bring to court ?

Proctor brings Mary Warren, to the court to tell everyone that the whole witch thing is fake. The judges ask for proof, and John tells them about his affair with Abigail.

Oh, Proctor also presents a deposition signed by Mary Warren that asserts this. Mary admits that her fits of bewitchment were pretense but later recants her confession out of fear of Abigail.
