After a dramatic drop early last year, the number of Central American children crossing the U.S.-Mexico border illegally has been rising sharply since April. Advocates say the increase is being driven by fears of gang violence at home — fears that outweigh heightened concerns about deportation under the Trump administration.“The reality is these children are not necessarily coming to the U.S., they’re just trying to get away from their home country,” said Catherine Hulme, project manager and attorney for unaccompanied children at the Pro Bono Resource Center of Maryland in Baltimore.
