Former President Donald Trump has issued a new executive order aimed at limiting birthright citizenship in the United States. This order follows a June Supreme Court ruling in Trump v. Barbara, which struck down an earlier, broader executive order denying citizenship to children born in the U.S. to undocumented immigrants and non-citizen parents on temporary visas.

The new order targets four specific categories of children, denying them birthright citizenship:

According to the Citizenship Clause of the Fourteenth Amendment, all children born or naturalized in the United States and subject to its jurisdiction are entitled to citizenship. The Supreme Court in Trump v. Barbara affirmed that this includes children of all persons subject to U.S. law. The new executive order, therefore, is considered unconstitutional by legal experts, as it excludes groups traditionally covered under the Citizenship Clause.

No part of the United States has been invaded or occupied since World War II, a fact relevant to the interpretation of "alien enemies" in this context.
