“People who didn’t like Billy Graham spent a lot of time trying to find personal violations of his moral and ethical code, and they couldn’t,” Wacker told NPR after Graham’s passing. “They didn’t exist. He was a man who maintained absolute marital fidelity and moral and financial integrity. He was an evangelist who lived the way he preached.”

"In 1950 he founded the Billy Graham Evangelistic Association in Minneapolis, Minnesota. Within a few years the civil rights movement began to sweep the nation. Billy, who had never really thought much about the plight of African Americans was instantly inspired to help the cause. He began refusing to speak or appear at events that were segregated. He joined the Montgomery Bus Boycott in 1955 where he met and befriended Martin Luther King, Jr. In 1957, Billy invited Dr. King to join him during a 16 week Christian event held at New York City's Madison Square Garden. This 16 week event attracted more than 2.3 million visitors from around the country and helped propel Dr. King and the Civil Rights movement into the mainstream conscience. Billy personally posted bail for Dr. King on several occasions after the MLK had been arrested during demonstrations."
