As promised, Gov. Rick Perry’s attorneys are asking a judge to dismiss the criminal charges against him.

They filed the motion in district court Monday morning. At a pre-trial hearing Friday, Perry’s attorney, David Botsford said the motion would attack the constitutionality of the prosecution. He says the law being used to prosecute Perry is too vague and that it violates the state’s constitution.

Gov. Perry is charged with two felony counts: abuse of power and coercion of a public servant. The charges stem from his threat to cut funding for the Public Integrity Unit, headed by Travis County District Attorney Rosemary Lehmberg. When Lehmberg refused to resign after her drunken driving conviction, the governor followed through on that threat and vetoed the funding.
