One-third of the population of Tapachula, Mexico, is now made up of migrants. Todd Bensman, a senior fellow at the Center for Immigration Studies, says the Biden-Harris administration negotiated it as a holding zone with the Mexican government, effectively making it a holding cell. But Bensman says that if Kamala Harris wins the election, the migrants will be free to travel to the United States after November. One caravan is even attempting to breach the U.S. border soon, in case Trump wins the election.
