Explanation:

The Palmer Raids is a 1919 event initiated by President Woodward Wilson. These actions were directed against immigrants from Italy and much of Eastern Europe for fear that they might proclaim the ideas of communism in the country. About 3,000 people were arrested in those raids, and more than 500 people were expelled from the country.

the doctrine of nullification recommended that states living inside the union have the one-sided, inalienable ideal to void any law made by the national government that could be esteemed illegal.

the united states was shaped based on a general agreement among its individual states. hence, it is inferred that under the hypothesis of invalidation, since the states are the establishment of the union, they have the ability to referee and disprove unlawful laws.
