A court-appointed monitor has revealed that a U.S. government program housing migrant children in hotels has grown and some of the children developed COVID-19. 

Using emergency health protocols, the Trump administration holds families and children who were traveling to the U.S. alone in hotels before expelling them from the country.

A federal court had appointed an independent monitor to oversee the government’s compliance with the Flores Settlement. That agreement manages how the U.S. cares for migrant children in its immigration custody.

The monitor noted that as recently as last month, 577 lone children were housed in 25 hotels in three states including Arizona and Texas.

She’s warned that at least three children developed COVID-19 while in the hotels. And she urged the court to no longer allow kids less than 15 to be held under the policy.
