WASHINGTON, D.C. (7News) — The Supreme Court heard arguments Thursday morning to consider whether lower courts have the power to block President Donald Trump's birthright citizenship order.

As oral arguments continue, it is clear that the high court is divided on which side to rule with.

How the justices leaned:

Some of the conservative justices, including Chief Justice John Roberts and Justice Brett Kavanaugh, seemed to lean towards President Trump's notion that lower courts overstepped their authority in blocking his executive order on birthright citizenship.

During the hearing, Justice Kavanaugh hinted that there are different ways that opponents can challenge Trump's rule, including class action lawsuits rather than lower court rulings.

On the other side of the court, Justices Ketanji Brown Jackson, Elena Kagan and Sonia Sotomayor, appeared to lean in favor of lower court rulings.

Sotomayor claimed that Trump's birthright citizenship order was violating the meaning of the Constitution and Kagan questioned what would happen to the people that this directly impacts if the block on the executive order was lifted.

How advocates feel:

As the case takes center stage, advocacy groups rallied in D.C. to support birthright citizenship.

“Birthright Citizenship is not a policy. It is not a law. It is part of the Constitution," said organizers of today's rally.

Background:

On the first day of his term, President Trump signed an executive order that would deny citizenship to children if neither parent is a citizen or a lawful permanent resident of the United States. However, lower court rulings put the push on a nationwide hold.

Many lawsuits followed, with the main focus on if the order violated the 14th Amendment of the Constitution, which reads: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”

The Supreme Court is not expected to make a final decision on the matter today.
