From the Highlights: "In early 2019, a number of journalists, attorneys, and migrant caravan supporters raised concerns in the media and in litigation that CBP [U.S. Customs and Border Protection] took improper actions against them as a form of harassment due to their work on the migrant caravan. We conducted this review to evaluate these allegations. [...] We made six recommendations to improve CBP's controls on placing and removing lookouts and sharing U.S. citizens' sensitive information with foreign countries."
