Jason Piccolo is a Department of Homeland Security whistleblower. He blew the whistle in 2015 on the review practices for potential sponsors of unaccompanied alien children. Some children were being placed with sponsors with violent criminal histories. Senator Chuck Grassley sent a letter to DHS regarding Piccolo’s allegations.
See Obama Administration Allegedly Releasing Unaccompanied Minors into Criminals’ Custody. Piccolo’s effects caused DHS to make changes to its process and procedures of vetting sponsors.
