About two dozen states have filed lawsuits against the Trump administration contesting the birthright citizenship order, which experts say violates the 14th Amendment.

Trump's order directs federal agencies to stop issuing citizenship documents to U.S.-born children of undocumented mothers. It also applies to mothers in the country on temporary visas, if the father is not a U.S. citizen or permanent resident.

A federal judge has temporarily blocked President Donald Trump’s executive order ending the constitutional guarantee of birthright citizenship regardless of the parents’ immigration status.
