Feds have paid undercover informants in migrant caravanNBC, Nov 20, 2018
WASHINGTON — The Department of Homeland Security is gathering intelligence from paid undercover informants inside the migrant caravan that is now reaching the California-Mexico border as well as monitoring the text messages of migrants, according to two DHS officials.
The 4,000 migrants, mainly from Honduras, have used WhatsApp text message groups as a way to organize and communicate along their journey to the California border, and DHS personnel have joined those groups to gather that information.
The intelligence gathering techniques are combined with reports from DHS personnel working in Mexico with the government there in an effort to keep tabs on the caravan's size, movements and any potential security threats.

In a statement, DHS Spokeswoman Katie Waldman said, "While not commenting on sources or methods, it would be malpractice for the United States to be ignorant about the migrants — including many criminals — attempting to enter our country. We have an obligation to ensure we know who is crossing our borders to protect against threats to the Homeland and any indication to the contrary is misinformed."
