President Trump is not completely against “chain migration,” first lady Melania Trump said in an interview that aired Friday.

The first lady’s parents obtained U.S. citizenship in August through the practice, in which adult U.S. citizens can request residency for their immediate family. The president, however, has repeatedly decried the policy.

“I believe in the policies that my husband put together because I believe that we need to be very vigilant [about] who is coming to the country,” the first lady told ABC News.

She said she believes that immigrants should be able to bring their parents to the U.S., as she did.

“But we need to vet them. We need to know who they are,” she said, adding that “of course” she has told her husband her stance and “he agrees.”

“Chain migration, he doesn't want to just cut it off completely. We need to vet the people, and we need to make sure that they believe in our system,” she said.

The president has repeatedly voiced opposition to the practice.

Trump’s parents, Viktor and Amalija Knavs, took their oath of citizenship in New York City after living in the U.S. as permanent residents. Their lawyer said the couple had been “sponsored by their daughter and then once they had the green card, they then applied for citizenship when they were eligible.”

To obtain citizenship, legal permanent residents are required to live in the U.S. continuously and hold their green cards for at least five years.
