Court ruling leaves fate of the US president’s order to overturn birthright citizenship rights unclear

The high court did not take up the underlying issue of whether President Donald Trump's order ending automatic birthright citizenship was constitutional.

The case stemmed from an executive order Trump signed when he took office that ended birthright citizenship.

Because of the ruling to limit injunctions, Trump's birthright citizenship order will be able to take effect, 30 days after the courts opinion was filed, the court said.
