A federal judge in Maryland blocked President Donald Trump's latest executive order restricting birthright citizenship on Wednesday.

U.S. District Judge Deborah Boardman granted a preliminary injunction barring enforcement of key provisions in the order Trump signed in August. The directive sought to deny citizenship to children born in the United States to foreign parents who engaged in a commercial transaction for citizenship or whose parents are classified as alien enemies.

Boardman, a Biden appointee, ruled that the new order conflicts with the Supreme Court's June decision in Barbara v. Trump. That 6-3 ruling struck down Trump's initial, broader executive order issued on his first day in office in January 2025, which aimed to end birthright citizenship for children of parents not lawfully present or on temporary visas.

"The Supreme Court has spoken," Boardman wrote. "The President must follow it." She described the administration's interpretation of the high court ruling as distorted and said the new order is almost certainly unconstitutional as applied to the certified class of plaintiffs.

The injunction applies to children born after Feb. 19, 2025, who fall under the class defined in the earlier lawsuit. It prevents agencies including the State Department, Homeland Security, and Social Security Administration from denying or failing to recognize their citizenship.

The Trump administration argued the new order addressed narrow exceptions left open by the Supreme Court and focused on combating birth tourism. Justice Department lawyers maintained it was not retroactive.

Immigrant rights groups that challenged the original order sought the new injunction. A separate challenge remains pending in New Hampshire.

The ruling marks another setback for the administration's efforts to limit automatic citizenship at birth under the 14th Amendment's Citizenship Clause. The case continues as the parties litigate the full merits.
