Barraza was arrested in April 2009, just months after he took office. He was indicted on charges of mail fraud, wire fraud and lying to a federal agent.
The video included testimony from Sarai Valencia. FBI agents equipped her with a portable hidden camera and a body wire. Valencia was expected back on the stand Friday.
Valencia testified, during cross examination, that she received $2,000 for helping the FBI build its case against Barraza.
