President Donald Trump hasn’t exactly made his dislike and distrust of immigrants a secret, with his comments about “bad hombres” coming over the border and his restrictions on Muslim people crossing into the U.S. Throughout his first and fortunately only term as president he’s also mentioned taking executive action targeting birthright citizenship, The Hill reports.

Apparently, drafts of such an order have been circulating for a while, and there have been discussions within the Trump administration that the order may be finalized before the Biden administration takes office in January, say two unnamed sources familiar with the discussions.

The Trump administration already knows the decision will be challenged immediately in court, but one source familiar with the situation said administration officials hope to get a ruling on whether the 14th Amendment protects birthright citizenship. It’s been argued by influential lawmakers and experts birthright citizenship is protected but the courts have issued definitive rulings on this issue.

“Since taking office, President Trump has never shied away from using his lawful executive authority to advance bold policies and fulfill the promises he made to the American people, but I won’t speculate or comment on potential executive action,” White House deputy press secretary Judd Deere said in a statement.

The birthright citizenship measure is being mulled over along with several other executive actions the Trump administration could take in its waning days. In the days after the election, White House Chief-of-Staff Mark Meadows has told aides to seek potential policy priorities that can be pushed through in the two months before inauguration day.

What are some of the policies being considered? Additional reforms to the H-1B visa program, and regulatory measures that target China. And on Friday Trump issued regulations aimed at lower prescription drug prices.

But birthright citizenship has been an issue Trump has returned to at least twice in the last five years, having proposed ending the practice that grants citizenship to infants of foreign-born parents who themselves are born in the U.S. He returned to this issue in an interview with Axios in 2018 and then again in August 2019 when he announced his administration was seriously looking at a measure to end birthright citizenship.

Trump has never made his nationalism and xenophobia a secret, with his comments about sh*thole countries and claims that white supremacists are “very fine people.”

And whether or not his attempts to limit birthright citizenship succeed or fail, or whether it’s undone by the Biden administration, some experts are worried this could further harm immigrants seeking a new life in the U.S.

“That’s going to have a deterrent effect on people who are seeking to come here, who may be present,” said Shev Dalal Dheini, director of government relations for the American Immigration Lawyers Association. “The goal of this administration with all of its policies is it doesn’t matter if the policy actually takes effect and becomes the law of the land, but it’s what is the deterrent effect on people in the interim.”

But that’s Trump in a nutshell. He doesn’t really care about who this could harm. In all likelihood, he’s hoping this will be another hurdle the Biden administration will have to jump over.
