Tony Mack got four years and 10 months, a term less than the federal guidelines but harsher than his lawyer requested. His brother, Ralphiel, received a 2.5 year term at Thursday's hearing.
Mack was convicted in February of extortion, bribery, and mail and wire fraud. He and his brother were caught in a sting operation in which FBI informants posed as businessmen trying to develop a parking garage.
In one unusual move, a woman who served as an alternate juror during the trial wrote a letter of support to the judge; Sherie Jackson heard all the testimony but did not participate in deliberations.
"Please, for the sake of true justice, spare these men a harsh fate," Jackson wrote.
Jackson told the judge she felt like the jurors who voted for conviction "had not been in the same courtroom" she was in.
Mack, who had already told the judge he had nothing to say before sentencing, did not talk to reporters after the sentencing. His lawyer, Mark Davis, said he has moved out of the area.
"After this is all over, he will probably never be able to find an actual career again," Davis said. "That has been stripped from him. Everything he has is gone."
