H. Ty Warner's sentencing will also give him a chance to apologize at length for hiding his millions in Swiss bank accounts.
The 69-year-old apologized and wiped away tears when he pleaded guilty last year. But the judge in Chicago stopped him and said he could explain himself fully at sentencing.
Defense attorneys have argued for probation, pointing to Warner's unhappy childhood and his charity work.
But prosecutors say Warner should spend some time in prison; they don't recommend how much.
