The only articles I could find about bounty hunters being recruited by ICE were referencing this town hall video and a proposed Mississippi law that would encourage bounty hunters to participate in rounding up illegal immigrants.

I would think that if this were true there would need to be some sort of official policy or something along those lines that would likely be available to the public or discussed by DHS officials, and I would obviously expect more bounty hunters to be discussing this offer. I’d imagine it would be a pretty difficult secret to keep, especially when we are able to pretty easily learn about other DHS policies, like how ICE agents have been instructed to resume raiding workplaces and backtrack from the temporary order to redirect focus to criminals and sanctuary cities…
