On Friday, the first day since March 2020 in which the U.S. could no longer cite Title 42 to expel migrants, Border Patrol apprehended 6,300 migrants, a sharp drop from earlier in the week.
Enrique Reina, the Honduran secretary of foreign affairs, identified the child as Ángel Eduardo Maradiaga Espinoza.
Migrants subjected to the rule could face deportation to their home country or Mexico as well as a five-year ban from the U.S.
The ruling raises the prospect of even higher numbers of migrants being stranded in Border Patrol custody in dangerously overcrowded conditions amid a spike in migrant arrivals.
An estimated 60,000 migrants were waiting near the U.S.-Mexico border as the Biden administration ended the Title 42 rule, the Border Patrol chief said.
Here are some of the top questions about the end of the policy known as Title 42, and what's happening at the border now that it has expired.
In border cities like El Paso, the spike in migration has alarmed volunteers and humanitarian workers who support welcoming and helping asylum-seekers.
The program, which will initially apply to migrant families heading to four U.S. cities, is part of a larger Biden administration effort to deter migrants from crossing into the U.S. illegally.
The operation is one of several steps the Mexican and U.S. governments are taking to stop or deter migrants from crossing the southern border illegally.
The rule represents a major pivot by President Biden, a Democrat who campaigned on restoring access to the U.S. asylum system.
The operation is aimed at many of the thousands of migrants who've been sleeping on El Paso's streets amid a spike in migrant crossings ahead of the end of Title 42 restrictions Thursday.
"The basic problem here is those laws need to be updated," White House senior adviser Anita Dunn said.
The proposal would effectively allow the U.S. government to continue the soon-to-be terminated Title 42 border expulsion policy without a public health justification.
Because it has relied on the Title 42 policy for over three years, the U.S. expects to see a sharp increase in immigration to the southern border once it expires.
The agreement will allow the U.S. to continue deporting some migrants who U.S. officials have struggled to deport to their home countries due to diplomatic or logistical reasons.
