The founder of a South Texas cargo airline has taken the stand in the fifth day of his federal trial on child pornography charges and described several people motivated to set him up.

Robert Hedrick told jurors Friday about disagreements with two business partners. Hedrick was running a global pool supply company and Brownsville-based Pan American Airways. He also described his wife's infidelities and the divorce he initiated shortly before being arrested last summer.

Hedrick is charged with five counts related to child pornography and sexual exploitation of children. If convicted, he could face up to 20 years in prison on just one count of distributing child pornography.

Hedrick's lawyers have said he is the victim of a conspiracy. The prosecution rested Thursday.
