Wong Kim Ark’s fight to be recognized as a US citizen 127 years ago led to an expansion of the 14th amendment

• What is US birthright citizenship and what does Trump’s executive order do?

In 1898, at the height of anti-Chinese hysteria, a young cook won a landmark supreme court case that guaranteed citizenship to anyone born on US soil, regardless of race or ancestry. Millions of children from immigrant households have since become United States citizens as a result of his legal battle.

The constitutional right that Wong Kim Ark helped cement has come under growing assault from conservatives. Mere hours after being sworn into office for a second presidential term last Monday, Donald Trump signed a slew of executive actions to fulfill his campaign promises, the chief among which was ending birthright citizenship. In a sweeping directive, Trump directed federal agencies to refuse citizenship to children born in the US if neither parent is a citizen or permanent resident.
