Why Do Giles and Francis Want to Talk to Danforth?

In Arthur Miller's "The Cruible," Giles Corey and Francis Nurse demand the opportunity to present evidence to Deputy Governor Danforth to exonerate their wives and prove that they aren't witches. Danforth agrees to hear their evidence, but doesn't commute the sentences.

Giles and Francis interrupt the witch trials to try to save their wives, who have been found guilty of witchcraft and sentenced to die. They believe that they can convince Deputy Governor Danforth to commute the sentences. Giles says that many of the accusations that Thomas and Ann Putnam made, including those against his and Francis' wives, were false. He says that the Putnams have little interest in ferreting out witches and want to buy the land of the condemned and those who are killed.

Both Giles and Francis are taken from the courtroom and placed in a vestry room. Here, Deputy Governor Danforth, Judge Hawthorne, and the Reverends Hale and Parris agree to hear from them. They say that they've waited three days to share evidence with the court that exonerates their wives and several other would-be witches, and Danforth says that all they needed to do was file the right paperwork. Reverend Hale asks for Thomas to have a chance to hear this evidence against him and refute it.

After Thomas joins the men in the vestry room, Giles is asked for the evidence he claims to have. When he refuses to reveal his source, Danforth holds him in contempt of court and arrests him. He is later pressed to death.
