Lawyers for accused CIA leaker Joshua Schulte asked for a mistrial in his case Tuesday morning, claiming prosecutors withheld evidence that could exonerate the former computer engineer, court filings show.

The 12-page classified filing asks Judge Paul Crotty for a mistrial “based on Brady and other violations” and provides no other information.

A 1963 court ruling in Brady v. Maryland requires prosecutors to disclose “materially exculpatory evidence in the government’s possession to the defense,” according to Cornell Law School.

That includes any evidence “favorable to the accused” and evidence that “goes towards negating a defendant’s guilt, that would reduce a defendant’s potential sentence, or evidence going to the credibility of a witness,” according to Cornell.

Crotty addressed the motion before the trial commenced Tuesday morning and asked the government how long it needed to respond.

It said it would respond by Wednesday.

Schulte is accused of being the mastermind behind the CIA’s largest loss of classified documents in its history in the dumps of “Vault 7” and “Vault 8” to WikiLeaks.

The people have accused Schulte of being a disgruntled employee who stole the confidential documents when he was upset about how the agency was handling internal complaints he filed against co-workers.

Schulte’s lawyers claimed that being a difficult employee doesn’t make someone a traitor.
