A former Texas district attorney is choking back tears as he recalls a prosecution that wrongfully sent a Texas man to prison for 25 years.

Ken Anderson calls the case of Michael Morton his "worst nightmare."

Morton was convicted in the slaying of his wife Christine in 1987 but exonerated in 2011 following new DNA tests.

Anderson is now a judge in Georgetown near Austin. He is accused of withholding evidence indicating Morton's innocence during the original trial. A special court of inquiry on the matter is in its fifth day Friday.

Anderson says he did nothing wrong. He says the office he "ran was professional, it was competent."

Then, his voice cracking, Anderson added, "We got it right as much as we humanly could."
