New government figures released Friday show that the U.S. Border Patrol arrested 51,856 individuals attempting to illegally cross the southern border in November. That's a 78 percent increase over the same period last year.
The escalating arrests represent a high-water mark for apprehensions under the Trump administration and the number of those apprehended are increasingly adults with children.
In November of last year, 7,016 "family units" were apprehended. In November 2018, the number of families arrested jumped almost four-fold to 25,172, while only 5,283 were unaccompanied children.
"The November 2018 border numbers are the predictable result of a broken immigration system – including flawed judicial rulings - that usurps the will of the American people who have repeatedly demanded secure borders," said Department of Homeland Security spokeswoman Katie Waldman said in an emailed statement.
Waldman blamed a recent ruling by a federal judge in San Francisco that blocked the Trump administration from requiring asylum seekers to present themselves at ports of entry.
"Unfortunately, individual district court judges in separate immigration rulings have given another free pass to illegal aliens to violate our laws. This has consequences," said Waldman.
She added that the increase in illegal border crossings is a key factor in the president's deployment of more than 5,000 troops to the southern border deter the migrant caravan originating in Central America.
U.S. Border Patrol data covering FY2000 to FY2017 shows that the last time more than 50,000 people were arrested at the southern border in the month of November was 2007. It was during the administration of President George W. Bush and 51,594 people were caught.
Back then, the unauthorized migrants were largely Mexicans. The current wave of migrants is increasingly from the Central America's "Northern Triangle" countries of Guatemala, Honduras and El Salvador.
