Detroit ? Mayor Kwame Kilpatrick pleaded for forgiveness from his family and his constituents Wednesday in an emotional televised speech, his delayed response to recently revealed racy text messages that contradict his sworn testimony that he did not have a physical relationship with a key aide.

“I truly apologize to you,” Kilpatrick said, turning to his wife, Carlita, who sat by his side, holding his hand, at their family church.

“I am the mayor. I made the mistake,” Kilpatrick told Detroit residents, looking into the camera. “I am accountable.”

He did not publicly specify, however, what he was apologizing for, saying legal matters prevented him from doing so.

A prosecutor is investigating whether the mayor and chief of staff Christine Beatty lied under oath during a whistle-blower’s lawsuit last summer in which both denied having a physical relationship. A conviction of lying under oath can bring up to 15 years’ imprisonment.

Kilpatrick vowed to remain mayor in the carefully orchestrated speech, which aired live in prime time on local television and radio stations. He closed by saying, “God bless you, Detroit. I love you. I will see you at work tomorrow.”
