Facing new accusations that he embezzled his own campaign funds, state Sen. Kyle Loveless resigned Thursday and admitted he made mistakes.

The conservative Oklahoma City Republican stepped down two days after his defense attorney, Mack Martin, met with Oklahoma County District Attorney David Prater about the accusations.

He became the third Oklahoma senator in the last two years to resign in disgrace after coming under criminal investigation. His resignation is effective immediately and is irrevocable.

A criminal investigation into his campaign finances has been underway since February.
