A federal judge has blocked an attempt by Trump to require proof of citizenship for voting. This decision overturns an order that mandated US citizens to provide documentary evidence of their nationality in order to cast their vote. The ruling effectively annuls the previous order, allowing citizens to vote without having to present proof of citizenship.
