ATLANTA (AP) — Lawyers for reality TV stars Todd and Julie Chrisley, who are in prison after being convicted on federal charges of bank fraud and tax evasion, on Friday challenged aspects of their convictions and sentences in a federal appeals court.

The Chrisleys rose to fame with their show “Chrisley Knows Best,” which chronicled the exploits of their tight-knit family. But prosecutors said they engaged in an extensive bank fraud scheme and hid their earnings from tax authorities while showcasing their extravagant lifestyle.

Peter Tarantino, an accountant they hired, also is serving time in prison. He wants his conviction thrown out and to be granted a new trial.

A three-judge panel of the 11th U.S. Circuit Court of Appeals in Atlanta on Friday heard arguments from lawyers for the three.

Two of the Chrisleys’ children, Savannah and Chase, were joined by more than a dozen supporters in the gallery of the courtroom. Savannah Chrisley spoke to reporters after the hearing, saying she talked to her parents Thursday night and that they are “doing as best as they can” and hope that Friday’s hearing is a step toward getting them home.
