ATLANTA (AP) — Todd and Julie Chrisley were driven by greed as they engaged in an extensive bank fraud scheme and then hid their wealth from tax authorities while flaunting their lavish lifestyle, federal prosecutors said, arguing the reality television stars should receive lengthy prison sentences.

The Chrisleys gained fame with their show “Chrisley Knows Best,” which follows their tight-knit, boisterous family. They were found guilty on federal charges in June and are set to be sentenced by U.S. District Judge Eleanor Ross in a hearing that begins Monday and is likely to extend into Tuesday.

Using a process to calculate a sentencing guideline range based on several factors, federal prosecutors determined the upper end of that range is nearly 22 years for Todd Chrisley and about 12 and a half years for Julie Chrisley. The couple should also be ordered to pay restitution, prosecutors wrote in a court filing.
