(TIJUANA, Mexico) — Central Americans who traveled in a caravan through Mexico to the border with San Diego began turning themselves to U.S. authorities to seek asylum Monday in a direct challenge to the Trump administration. Nearly 200 migrants, many traveling with children, decided to apply for protection at the nation’s busiest border crossing after many fled violence in their home countries, organizers said. Wendi Yaneri Garcia says she’s confident she will be released while her asylum case winds its way through the courts because she’s traveling alone with her 2-year-old son, who has been sick. “All I want is a place where I can work and raise my son,” the 36-year-old said. She said police in her hometown of Atlantida, Honduras, jailed her for protesting construction of a hydroelectric plant and that she received death threats after being released. President Donald Trump and members of his Cabinet have been tracking the caravan of migrants, calling it a threat to the U.S.
