A federal judge questions the Trump administration on implementation plans for controversial birthright citizenship executive order as advocacy groups file class action lawsuits in response.

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.

The ruling left unsettled the question of whether children born to immigrants without full legal status in the United States are entitled to automatic citizenship. So what happens now?
