As thousands of migrant children have been taken from their parents and sent to facilities across the country, questions are growing about the medical care they are receiving—or, as health experts fear, not receiving. Since President Donald Trump’s “zero tolerance” policy for unlawful entry into the country went into effect in April, more than 2,300 children, including infants, have been forcibly separated from their parents. Although Trump last week ordered families to now be detained together, federal officials from several agencies have refused to give any information on the children’s welfare or what medical care they’re receiving.
