At a Monday press conference, Tom Homan, Donald Trump’s immigration adviser, disputed the use of the term “deported” to describe what occurred.

“They weren’t deported. We don’t deport U.S. citizens. Their parents made that decision, not the United States government,” he said, as reported by the BBC.

“Having a U.S. citizen child does not make you immune from our laws,” Homan added, emphasizing that the mothers were in the country without legal status.

In Trump’s first 100 days back in office, thousands of undocumented immigrants have been taken into custody, as part of his renewed pledge to overhaul U.S. immigration policies.

On Monday, White House Press Secretary Karoline Leavitt stated that the administration’s immigration enforcement efforts had seen early success.

Leavitt also announced that Trump plans to sign two new executive orders. One of them will require the government to publish a list of so-called “sanctuary cities,” referring to jurisdictions that limit cooperation with federal immigration enforcement.

“It’s quite simple,” she said. “Obey the law, respect the law, and don’t obstruct federal immigration officials and law enforcement officials when they are simply trying to remove public safety threats from our nation’s communities.”
