San Mateo County Sheriff Christina Corpus delivered emotional testimony Tuesday as she continued her defense in a hearing that could determine whether she remains in office.

On the first two days of the hearing, attorneys for the county, represented by San Francisco law firm Keker, Van Nest, & Peters, sought to portray Corpus as a vindictive leader who retaliated against critics and blurred lines between her professional duties and personal relationships.

Philip testified that he was ordered to arrest Carlos Tapia, the president of the San Mateo County Deputy Sheriff's Association union and an outspoken critic of the sheriff, without a warrant. Corpus directed the arrest, citing suspicion of timecard fraud.
