San Antonio attorney Michael McCrum on Aug. 19 took the oath of office to serve as an attorney pro tem to investigate allegations that Gov. Rick Perry committed crimes when he vetoed funding for the Travis County District Attorney's Public Integrity Unit.

Senior judge Bert Richardson, who is overseeing the matter, appointed McCrum to the position. He will take the role of a district attorney to investigate the allegations in a Complaint that alleges Perry threatened to veto the funding unless Travis County DA Rosemary Lehmberg resigned her position. The complaint, filed by advocacy group Texans for Public Justice, alleges Perry committed coercion of a public servant or voter, bribery, abuse of official capacity and official oppression.
