A Nebraska man has been convicted of a federal bribery charge along with a former Chicago alderman and another man.

Jurors convicted 71-year-old Jim Barta, 59-year-old former alderman Ambrosio Medrano and their friend 50-year-old Gus Buenrostro on Monday.

Prosecutors say the three men agreed to bribe an undercover FBI agent posing as a purchasing agent for a California hospital to land a pharmaceutical contract.

Barta is a cattle rancher who lives in Fremont and owns the Sav-Rx prescription company.

The three men had argued they were entrapped by FBI agents who came up with the hospital contract deal, but the jury rejected that argument.
