Educated on a legal loophole that lets migrant “families” with kids enter the United States, the Homeland Security Department reported Tuesday that men showing up with kids at the border has spiked 110 percent in just the last two years.

The department noted that children could be used by smugglers and drug traffickers to enter the country.

Families are also using fraud to game the immigration system. The department said that 170 families have been caught lying about their relationships to enter the U.S.

“This data does not show nor does DHS assert that all minors apprehended as part of a family unit are illegitimate, but it does indicate that there is a significant problem that provides DHS the needed authority to protect the best interests and welfare of all children,” said the department.

The statement was aimed at news reporting that has suggested the Trump administration is tear gassing and rejecting families.

Spokeswoman Katie Waldman said:

She also supplied some numbers to back up the fraud charges:

• 87 family units separated based on child determined to be over 18.

• 165 adults and 6 individuals that had initially claimed to be minors but were later discovered to be adults.

• 170 family units separated based on no family relation.

• Overall, the Rio Grande Valley had the highest number of reported fraudulent cases (170).
