The Supreme Court heard its first set of Trump-related arguments in the second Trump presidency on Thursday.

The case stems from the executive order President Donald Trump issued on his first day in office that would deny citizenship to children born on U.S. soil to parents who are in the country illegally or temporarily. The executive order marks a major change to the provision of the 14th Amendment that grants citizenship to people born in the United States, with just a couple of exceptions.

Immigrants, rights groups and states sued almost immediately to challenge the executive order. Federal judges have uniformly cast doubt on Trump’s reading of the Citizenship Clause. Three judges have blocked the order from taking effect anywhere in the U.S., including U.S. District Judge John Coughenour. “I’ve been on the bench for over four decades. I can’t remember another case where the question presented was as clear as this one is. This is a blatantly unconstitutional order,” Coughenour said at a hearing in his Seattle courtroom.

Nevada is among several other states suing to block President Trump's executive order. 

After arguments finished, Nevada Attorney General Aaron D. Ford and 19 other attorneys general issued a joint statement: 

"The Supreme Court is taking up emergency appeals filed by the Trump administration asking to be able to enforce the executive order in most of the country, at least while lawsuits over the order proceed. The constitutionality of the order is not before the court just yet. Instead, the justices are looking at potentially limiting the authority of individual judges to issue rulings that apply throughout the United States. These are known as nationwide, or universal, injunctions."

Birthright citizenship automatically makes anyone born in the United States an American citizen, including children born to mothers in the country illegally. The right was enshrined soon after the Civil War in the Constitution’s 14th Amendment.

Trump and his supporters have argued that there should be tougher standards for becoming an American citizen, which he called “a priceless and profound gift” in the executive order he signed soon after becoming president again in January.

The Trump administration has asserted that children of noncitizens are not “subject to the jurisdiction” of the United States, a phrase used in the amendment, and therefore are not entitled to citizenship.

A decision should come relatively soon. The Supreme Court typically rules in all its argued cases by the end of June and this one shouldn’t be any different. If anything, an order from the court might come quickly because the legal issue before the justices is not whether Trump’s birthright citizenship restrictions are constitutional, but whether to grant the administration’s emergency appeals to narrow lower court orders against it while lawsuits proceed.
