Can Trump limit birthright citizenship? Legal experts are doubtful

Donald Trump has issued a new executive order aimed at curbing "birth tourism." However, legal experts express doubt about its legality, citing a previous Supreme Court defeat on a similar issue. The article suggests this new order will face significant legal challenges. The "why" behind the order is to target individuals who travel to the United States to give birth, presumably to obtain citizenship for their children. The "when" is implied to be recent, given the mention of a "new order." The "who" are Donald Trump (issuing the order) and legal experts (expressing doubt). The "what" is the executive order and the ensuing legal uncertainty.
