The Trump administration plans to pay a Texas nonprofit nearly half a billion dollars this year to care for immigrant children who were detained crossing the U.S. border illegally, according to government data. The nonprofit, Southwest Key Programs Inc., is to be paid more than $458 million in fiscal 2018, according to the data — the most among the organizations, government agencies and companies that run a detention and care system for immigrant children on behalf of the Department of Health and Human Services.
