Relating to reporting regarding the confinement in the Texas Department of Criminal Justice or a county jail of certain persons not lawfully present.

HB 4878 requires the Texas Department of Criminal Justice (TDCJ) and county jails to report on the confinement of individuals not lawfully present in the U.S. (referred to as "illegal criminal aliens" in the bill). Specifically, TDCJ must submit an annual report by January 31 detailing the number, cost, and facility occupancy impact of these individuals confined in TDCJ facilities. County jails must submit monthly reports including a specific category for "prisoners for whom an immigration detainer has been issued." The bill mandates reporting on metrics like total confinement costs, facility capacity usage, and estimated costs for remaining sentences. These requirements apply directly to state and county correctional facilities operating under Texas law.
