New birthright citizenship challenges filed in wake of Supreme Court ruling

• But the order left room for broader relief through the filing of class action lawsuits.

Driving the news: Following the ruling Friday, the plaintiffs — CASA Inc., the Asylum Seeker Advocacy Project and a group of expectant mothers — asked a federal judge in Maryland to block Trump's executive order attacking birthright citizenship.

• "Without a class-wide injunction, Defendants will deny thousands of babies in the putative class their constitutional and statutory right to United States citizenship, as well as all of the rights and privileges that citizenship entails," the complaint states.
• The Supreme Court indicated in its Friday order that class action lawsuits are among the permitted methods to block federal government policy.
• "Consistent with the Supreme Court's most recent instructions, the Court can protect all members of the putative class from irreparable harm that the unlawful Executive Order threatens to inflict," the suit states.

Catch up quick: Trump signed an executive order on his first day in office this year, seeking to end birthright citizenship for children born in the U.S. to noncitizen parents and undocumented immigrants.

• The order was quickly met with legal challenges, which resulted in temporary blocks on the order's enforcement nationwide.
• Trump's DOJ asked the Supreme Court to limit the scope of those orders, and the high court on Friday imposed such limits on lower courts' ability to freeze federal policies.

What they're saying: "This is a sad day for everyone who believes in the rights enshrined in the U.S. Constitution, especially expecting immigrant parents who only want their children to have the same rights as other children born in the U.S." Swapna Reddy, co-executive director of the Asylum Seeker Advocacy Project, said in an emailed statement.

• "But the fight to defend birthright citizenship is far from over," Reddy added.
• CASA Inc. did not immediately respond to Axios' request for comment.
