The surge in migrants adds to a growing sense of emergency for the Biden administration which has been seeking to unwind the Trump administration’s immigration policies over that time.
“February was unprecedented compared to the last five years,” a Homeland Security official told CNN. Single adults make up the biggest portion of apprehensions, but the percentage of families and children jumped last month, according to the official.
Since last April, Customs and Border Protection has seen an increase in border encounters from the Western Hemisphere due to worsening economic conditions brought on by the pandemic and natural disasters in the region, according to the border agency.
Border arrivals typically rise in the spring, but the Covid-19 pandemic has exacerbated the situation and further limited the capacity along the border to process migrants. Last year, the numbers dropped in March and April as the pandemic took hold and travel restrictions were put in place.
However, under the Biden administration, unaccompanied children are exempt from the order and are allowed to remain in the US pending immigration cases. Some families and others have also been allowed to remain in the US due to changes in Mexican policy and case-by-case determinations.
CNN has reached out to DHS and CBP for comment.
A CBP spokesperson previously said, “The unique challenges of the pandemic require additional authorities, such as the CDC order known as Title 42, to allow DHS to effectively protect both the health and safety of migrants and our communities from the spread of COVID-19. The border is not open, and the vast majority of people are being returned under Title 42.”
More than 3,200 unaccompanied migrant children were in Customs and Border Protection custody, according to the documents dated Monday.
That was around half of the total number of people in custody, which was over 6,500 as of Monday morning, the DHS official said. About half of the number of children in custody were in the Rio Grande Valley region of Texas, the official added.
“The number of kids is alarming and concerning and not good and not good at all,” the official added.
Border authorities are encountering 4,000 to 5,000 people daily, the official said, adding that just over 500 are unaccompanied children.
There are ongoing discussions about the potential need for additional funding to resource the missions at the border, another Homeland Security official told CNN, saying officials are discussing the possibility of a reprogramming request or supplemental request for funding to Congress in the coming weeks and months.
“If we have increased migrant flow, there will be an increase in the need to deal with undocumented immigrants that come the US,” said the official. “If there is a surge in support, who is going to be paying for that?”
