Trump administration plans to expand DNA collection at the border

The Trump administration is planning to expand the collection of DNA from migrants who cross U.S. borders, and to include the information in a massive criminal database operated by the FBI.

The effort is separate from and much broader than the rapid DNA testing done on families at the U.S.-Mexico border to help detect adults falsely posing as parents. Not much else is known yet about the increased testing, including its purpose and whether it would apply to children crossing alone or to asylum seekers.

Two senior Homeland Security officials, speaking Wednesday to reporters on condition of anonymity to discuss an ongoing effort, said the Department of Justice was crafting new regulations and details were being discussed in a working group, but it’s not known when it would be implemented.


The collection comes after a huge increase in the number of people crossing the border, mostly Central American families. Officials have since said the numbers went down following crackdowns, changes in asylum policy and agreements with Central American countries, but border officers and agents have voiced concern over the potential for criminals crossing while resources were stretched.

The practice would allow the government to amass a trove of biometric data on migrants, raising major privacy concerns and questions on whether such data should be compelled even when a person is not suspected of a crime other than crossing the border illegally.

“It’s not surprising, given this administration’s fixation on villainizing folks at the border, but it reaches beyond them,” said American Civil Liberties Union attorney Vera Eidelman. DNA also contains identifying information on their families too.

Eidelman said it changes the purpose of DNA collection from one of criminal investigation to population surveillance.

John Hunter believes in Trump. His wife, Laura, a Mexican immigrant, says Trump is ‘despicable.’ Working to save lives at the border keeps them together.

A top Border Patrol official recently warned that expanding DNA collection at the border could hurt the orderly processing of migrants. In a written deposition in a case involving families separated at the border, Brian Hastings, chief of the Border Patrol’s law enforcement directorate, addressed whether DNA would be a good tool for identifying families and should be expanded.

“Even once such policies and procedures were put in place, Border Patrol Agents are not currently trained on DNA collection measures, health and safety precautions, or the appropriate handling of DNA samples for processing,” he wrote.


DNA collection is noninvasive, and done mostly through a cheek swab to collect saliva, or a bit of hair, but proper collection and sample storing require training. It’s not clear how many officers would be trained in collection.

Right now, migrants who cross the border illegally are fingerprinted, and those fingerprints are sent to federal databases accessible by state and local law enforcement agencies.

DNA can be taken if a person has been arrested on federal charges. Crossing the border between ports of entry is considered a federal crime.

Law enforcement agencies can submit samples to the FBI from suspects who are arrested or convicted of state or federal crimes and from non-U.S. citizens who are being detained by the government. The FBI’s national DNA index contained more than 17 million profiles from arrestees and other offenders as of August.

The L.A. Times finds the Trump administration appears to be violating U.S. law in implementing the Remain in Mexico policy, officials and lawyers warn.

Some police departments collect samples without a warrant from people who are never arrested or convicted of crimes, although the person is supposed to voluntarily provide a sample in those cases and not be coerced or threatened. State and federal authorities typically require a conviction or an arrest before a sample is taken.

The DNA fingerprint act of 2005 allows federal agencies to collect DNA from individuals in their custody, including those who are not American. It’s not a requirement, and Homeland Security has not collected DNA samples in vast numbers.


In 2010, then-Homeland Security Secretary Janet Napolitano directed that people held on administrative proceedings — not detained on criminal charges — and those facing deportation proceedings would not have DNA collected.

Broader sampling “would severely strain the resources of the agency to perform its broader mission,” Napolitano wrote in a letter to then-Atty. Gen. Eric Holder.

The new regulations would bring new protocols.
