In April 2017, O'Halleran criticized Attorney General Jeff Sessions's tougher new guidelines on expelling illegal immigrants who belong to criminal gangs. He said: "I have no problem with getting the felons out of the country. But some of these people that they're taking out of the country, they have children that are Americans, and they have not had a violent felony conviction. Here we are, taking mothers away from their children."
