As it pushes to implement a plan to end birthright citizenship, the Trump administration is counting on an argument about out-of-control federal judges to prove irresistible to some Supreme Court conservatives.

The Trump administration asked the Supreme Court to stop appeals court rulings that blocked Trump’s order to end birthright citizenship, which would deny U.S. citizenship to children born in the U.S. if their parents are undocumented or on temporary visas.

The Trump administration asked the Supreme Court for an emergency intervention Thursday limiting lower court rulings that are blocking President Trump’s plans to restrict birthright citizenship. The Justice Department’s ask comes after three federal appeals courts blocked the administration from moving forward.
