On Wednesday, August 22 and Thursday, August 23 "World News with Diane Sawyer" aired a two-part report " Inside the Mormon Church" from ABC's Dan Harris .

In introducing the series Diane Sawyer said - "It's a time of change in America. In the last 12 years alone we have seen the election of the first black President, the first Jewish candidate on a major ticket - Senator Joe Lieberman, and next week, another breakthrough - the first Mormon nominee for President, a profound and historic moment for the Mormon faith, which is a still a mystery to a lot of people. So tonight, Dan Harris begins a two-part series, answering questions about this uniquely American religion."

Harris notes in his report that "Mormons, who make up just 1.7 percent of the U.S. population, roughly equal to the number of Jews and double that of Muslims and Buddhists, are trying to be more open."
