The cio, which had a long history of communist members, purged over 1 million workers from its ranks during the red scare

The correct answer is true.

It is true that the CIO, which had a long history of Communist members, purged over 1 million workers from its ranks during the Red Scare.

CIO stands for Congress of Industrial Organizations. Founded by John L. Lewis in 1938, in Pittsburgh, Pennsylvania, he became the first President. It started with 4 million members and by 1945, membership in the number of workers had risen to 6 million.  However, during the Red Scare, -the accusations of Republican Senator for Wisconsin's Joseph MacCarthy about Communists infiltration in the federal government- the CIO had to expel 11 affiliated unions for having ties with Communists.

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.
