Soon after Nixon's selection, controversy erupted over the senator's 1951 purchase of a home with a restrictive covenant that forbade resale or rental to Jews. Chotiner, a Jew, successfully appealed to the Anti-Defamation League and the Jewish press for support for Nixon in the controversy, providing them with a list of Jewish causes which he had favored. Nixon's staff pointed out that the covenant was, in any event, invalid because of the U.S. Supreme Court's 1948 ruling in" Shelley v. Kraemer". The controversy "failed to gain fatal traction" but repeatedly surfaced in later Nixon campaigns.
