UPDATE, 12:15p ET: Gov. Perry entered a plea of 'not guilty' Wednesday to felony charges of abuse of power.

A defiant Gov. Rick Perry (R) turned himself in to authorities in Travis County, Texas, on Tuesday, not appearing all that worried about the case against him.

Perry was greeted by a crowd of supporters, some with signs, before he was booked and fingerprinted on charges of abuse of power.

Then he spoke to the crowd, calling the charges an injustice and an attack on the constitutional powers of the governor.

"I'm going to fight this injustice with every fiber of my being and we will prevail," he said.

Then, he went for some ice cream:

Perry, considered a contender for the 2016 presidential nomination, is accused of abusing his power by vetoing $7.5 million in funding for the state's public integrity unit.

It came after Travis County District Attorney Rosemary Lehmberg, a Democrat, refused to resign following a drunk driving arrest. The ethics unit is housed under Lehmberg's office and Perry had called for her to step down.

Perry has called the charges politically motivated, maintaining that the veto was within his powers as governor.
