The career of Richard Nixon unfolded amid significant political controversy, beginning with his roles in the House and Senate during the post-World War II era. He gained national prominence as a staunch anti-Communist, notably during the McCarthy era. His presidency became marred by the Watergate scandal, which involved a break-in at the Democratic National Committee headquarters. The ensuing cover-up led to public outrage and congressional investigations, resulting in Nixon's resignation in 1974. This controversy tarnished his legacy but underscored the importance of ethics in politics and governance, shaping future political campaigns.
