Williamson County District Attorney John Bradley testified this morning before the Senate Criminal Justice Committee about his role as the new chairman of the Texas Forensic Science Commission.

Bradley, who told the Tribune last week about his plans to reform the commission, expected some verbal jousting with the committee’s chairman, State Sen. John Whitmire, D-Houston, and others on the committee. He was right.

Here are two audio clips: Bradley’s opening remarks, which were interupted a few times for questions, followed by an exchange with Whitmire.

We’ll have complete video and audio stories later today.
