A federal judge has ordered the Trump administration to explain how it will enforce President Trump's executive order seeking to eliminate birthright citizenship.

The court's decision left enough room for the challengers to Trump's directive to try to prevent it from taking effect while litigation over its legality plays out.

Three days after the Supreme Court said litigants attempting to get court orders broadly blocking President Donald Trump’s policies must do so through class action lawsuits, an administration lawyer said it plans to oppose such legal maneuverings in cases challenging the executive order seeking to end birthright citizenship.
