Background: The elected District Attorney of Travis County, where Austin, the capital of Texas, is located is the head of the "Public Integrity Unit" of the state. This "Public Integrity Unit" has taken it upon itself to be the policing arm of ALL elected officials in the State of Texas, when Democrat Ronnie Earle was the elected DA in Travis County.
DA Earle promptly started attempting to go after Republicans, wielding the power of his office as a cudgel for political purposes, culminating in the indictment of Rep. Tom Delay, who was charged with something that was not a crime at the time he performed the act.
The current occupant of the office, DA Rosemary Lehmberg continued the partisan actions of attacking Republicans she thought she could get away with. However, she is also a raging drunk. One night, she decided to get into her car after getting to almost 3x the legal alcohol driving limit, and she got caught.
She promptly attempted to get the Sheriff's Department to call "Greg" (Hamilton, the elected Sheriff) of Travis County. When told that she had been arrested for Drunk Driving, she told the Sheriff's department employees "well, that's you're all's problem." The implication is clear: Give me special treatment because I know your boss.
When the head of the Public Integrity Unit refuses to resign after engaging in an attempt to subvert justice because of her position, it's time to disband that office. Governor Rick Perry had every right to use his line item veto to remove funding for the public corruption actions of the office, when the head of that office herself attempted to engage in public corruption to save her own skin.
