Anti-trafficking activist exposes how ‘slave ledger’ is being used by smugglers to control migrants

An anti-smuggling activist is sharing what he says is a ledger by smugglers of their victims and how much they owe to the cartels, shining a light on the border crisis.

As some men in the group fled, the logbook ended up being discarded, he says, and picked up by his team. Adam Shaw is a politics reporter for Fox News Digital, primarily covering immigration and border security.

"It's for all intents and purposes, it's a slave ledger," he says.
