After the publication of an investigative series in the "National Guardian" and the formation of the National Committee to Secure Justice in the Rosenberg Case, some Americans came to believe both Rosenbergs were innocent or had received too harsh a sentence, particularly Ethel. A campaign was started to try to prevent the couple's execution. Between the trial and the executions, there were widespread protests and claims of antisemitism; the charges of antisemitism were widely believed abroad, but not among the vast majority in the United States. At a time when American fears about communism were high, the Rosenbergs did not receive support from mainstream Jewish organizations. The American Civil Liberties Union refused to acknowledge any violations of civil liberties in the case.
