President Trump was beaming as he addressed reporters at the White House briefing room podium, calling it a "big, amazing decision" which the administration is "very happy about". He said it was a "monumental victory for the constitution, the separation of powers and the rule of law". The court's decision not only impacts Trump's birthright citizenship order, but also emboldens him to enact many of his other policy actions that have been temporarily thwarted by similar injunctions.

The Supreme Court has opened the door for the Trump administration to no longer grant automatic citizenship to everyone born on American soil – at least for the moment. Now the White House will have to implement its plan, which will be no easy task. On Friday, the nation's highest court allowed Donald Trump's executive order to end birthright citizenship to go into effect in a month's time, while leaving room for lower courts to curb the impact on those who have standing to sue. States traditionally handle processing birth certificates, and many do not record the citizenship of the parents. Democratic-run state governments will be in no rush to do so, no matter what the Trump administration may desire. And Justice Amy Coney Barrett, writing for the majority, left the door open for states to make the case that a more broad block on Trump's birthright citizenship action is necessary. That sets up big legal battles to come. (BBC)
