Change that Federal Prisoners being held for child pornography should have no rights to have any contact with Children

Federal Prisoners being convicted of child pornography should have no rights to be able to visit with and or contact children, whether they are biological children of the offender. Or children of the offenders significant other. As of right now, a prisoner can have unsupervised phone contact with a minor and it be legal. This must change, kids are being effected by this daily and though it may not be physical harm, sometimes the mental harm is much worse and can do more damage to the person in the long run.
