Stephen Miller blasted Supreme Court justices over birthright citizenship ruling, arguing no legitimate interpretation of the 14th Amendment extends to children of foreign nationals.

"If your ruling requires you to suicide your civilization, your reading of the constitution is wrong," Miller said, calling it impossible to apply the amendment to "foreigners with foreign loyalties, foreign citizenship, foreign obligations, foreign everything."

The comments come as the administration continues challenging automatic citizenship for children born on U.S. soil to non-citizen parents—a doctrine upheld by courts for over a century.
