A US judge has issued a new order blocking Donald Trump’s effort to curtail birthright citizenship, in the first legal challenge to the policy since the Supreme Court allowed it to move forward last month.

Even if the mothers' immigration statuses were called into question and even if Trump was not married to them at the time of the children's births, all of Trump's children have an American father. Thus, Trump's executive order against birthright citizenship would not affect the statuses of his own children.
