FBI Agent Testifies at Liu Campaign Fraud Trial

As treasurer for the John Liu campaign, defendant Jia "Jenny" Hou was trained to comply with New York City's Campaign Finance Board's rules - rules she's accused of breaking.

The prosecution called Adam Schafenberg on Thursday, the former CFB staffer who trained her in March 2011.

The second witness was special agent John Chiue, out of the FBI's Houston division, who posed as a wealthy restaurant consultant from Texas looking to buy access to power in City Hall. The government played video and audio from his meetings with the other defendant, Oliver Pan, to show how they hatched a straw donor scheme so the “businessman” could pump money into the Liu campaign.

But in the final audio played Thursday, Pan hesitates. "Are you sure you want to do this?" he asks the agent. His testimony resumes Monday.
