One of the most famous evangelist scandals involved Canadian-born Aimee Semple McPherson in the 1920s, who allegedly faked her own death. She later claimed that she had been kidnapped, but a grand jury adjourned with no indictment, saying it had not enough evidence to proceed. She died in 1944 from an accidental overdose of barbiturates.
One of the first televangelists, Aimee Semple McPherson once gave a speech in a speakeasy (similar to this video but not captured on film). Part of The Eloquent Woman blog's "Famous Speech Friday" series.
