VP JD Vance says the Supreme Court's 5-4 ruling blocking the birthright citizenship executive order shows the policy is "hanging by a thread."

Vance noted the narrow margin defied predictions of an 8-1 defeat, calling birthright citizenship "an absurdity" and "a loophole that rewards illegal aliens just because they have a baby in the United States while they are in our country illegally."

He told Fox's Laura Ingraham the administration will "keep fighting" to reverse the decision, comparing it to other overturned precedents.

The 5-4 stay temporarily blocks the order while lower courts review the case. Chief Justice Roberts joined the four liberal justices in the majority.
