 She faced five years in prison and a $10,000 fine before the Supreme Court overturned the conviction.In the 1960s, she again faced imprisonment and a hefty fine under a piece of McCarthy-era legislation known as the McCarran Act, when she and others refused to register as agents of a foreign government (the logic being that the CPUSA was under the control of the Soviet Union).In 1965, the Supreme Court reconsidered an earlier decision and found the registration provision to be in violation of the Fifth Amendment guarantee against self-incrimination.
