The Supreme Court heard oral arguments today in a case challenging President Trump’s executive order ending birthright citizenship. In an unprecedented move, President Trump attended today’s hearing in person, becoming the first sitting president to do so. The outcome of the birthright citizenship case has divided conservative legal scholars. Some are skeptical that the justices will reconsider how the 14th Amendment has been interpreted for decades to automatically grant citizenship to anyone born in the United States. When you read the debate that took place in Congress when the 14th Amendment was drafted, it seems clear that members of Congress only intended to make sure the children of former Black slaves would be considered U.S. citizens.
