UPDATE: In an op-ed published earlier this week, Senator Jeff Sessions (R-AL) offers further warnings about the legalization of criminals:
The sponsors promised that those "with a serious criminal background or who pose a threat to our national security" would be ineligible for legal status. But the bill allows the Homeland Security secretary, under certain conditions, to grant it to gang members; those with major misdemeanor criminal convictions (including felonies pleaded to misdemeanors) for serious crimes, including drug offenses, sexual abuse and prostitution; those with arrest records of any length; fugitives from deportation orders; or those who have been deported and illegally reentered.
