SCOTUS lets Rump end birthright citizenship in 28 states

[Speedy]

from CNN:

"The Supreme Court on Friday backed President Donald Trump’s effort to curtail lower court orders that have hampered his agenda for months. However, it also signaled that the president’s controversial plan to effectively end birthright citizenship may never be enforced."

Hopefully CFDT cannot do only what he wants, but assuming they let him end birthright citizenship in these 28 states and later the other 22 states prevail and find out his executive order was unconstitutional, what happens to the children born during this transition period? Can they get citizenship retroactively?

Each district will have to get a district wide injunction.  Nothing will happen as far as birth right citizenship until the SCOTUS rules in the end.
