We start with a clash between old fashioned values and reality TV scandal. Josh Duggar and his family are portrayed as a picture of wholesome perfection now. The show has been puld as josh faces accusations he sexually molested rurnd under aged girls when he was a teenager. This is the story of my family. We're the duggars. The family has been portrayed on "19 kids and counting" as a wholesome Christian family values. No cursing, and above all no premarital sex. We decided there was no kissing before marriage. Reporter: Now they are a family under fire. After allegations surfaced their oldest child, josh Duggar had inappropriate contact with several under aged girls beginning when he was 14 years old. The family presented itself as the perfect all-american Christian family. All of a sudden, most of the most salacious things you could imagine, which is child molestation goes in and people can't help but look. It's like watching a train wreck. Reporter: Stunning by reality TV standards. The news came to light when "In touch" magazine obtained a decades old police report detailing the incident. He was investigated for multiple sex offenses including forcible fondling against five girls in 2002 and 2003. A female minor claimed he touched her genitals while she slept. The statute of limitations expeered. The a judge ordered the original report be expunged from his record and destroyed. It's complex and often these issues remain a secret. Families don't know how to deal with it and in some cases don't deal with it at all, which is the worse-case snare row. Reporter: The allegations were acknowledged by josh Duggar himself, writing on Twitter and Facebook, I acted inexcusably for which I'm extremely sorry and deeply regret. I hurt others including my family and close friends. He said his parents arranged for him and the young girls to receive counseling and he knew if I continued down this wrong road I would ruin my life. Juvenile molesters are not in the same category. That's why it is important to realize if they get treatment early on it is possible for them to get better. Reporter: Josh's parents Jim bob and Michelle Duggar saying when josh was a teenager he made some very bad decisions and that dark and difficult time caused us to seek god like never before. There is so much shame when something like this happens. The parent S blame themselves and they are blaming the person victimized. It is a complex issue to address. I josh Duggar, the executive director of family research council action in Washington, D.C. Reporter: In his many public appearances, josh Duggar touted his conservative family image. As a father of three my wife and I are blessed to have our children butch I don't want them to grow up in America where they cannot live out their religious convictions without the government trampling on their rights. Reporter: He got married to his wife Anna on the show in 2008. I take I Anna to be my wedded wife. Reporter: The couple proudly waiting until they said "I do" to even kiss for the first time. Juju Chang interviewed them at the Texas home schooling conference where they met. There are many definitions of courtship, but for us it meant choosing purity, choosing to wait for a lot of things that people would take for granted. Our first kiss was our wedding day. Reporter: Okay. All right. That's what it meant for us. Reporter: And that is expecting the fourth child a baby girl next month. Her pregnancy has been a plot line on the show. Push, baby, push. Reporter: Many of the 19 Duggar children have become celebrities in their own rite with instagram followings, appearances on the covers of "People" and us weekly and their pregnant sis and births followed as closely as the kardashians. They have millions of people watching them. It really gets the ratings for them and a buzz show on social media. I'm josh Duggar. Reporter: Two years ago, josh accepted a high-profile job with the family research council. I believe every child deserves a mother and father. I'm sure grateful for mine. Reporter: A deeply conservative lobbying group, devoted to promoting a Christian world view. Oldest dug Ar was one of the public faces of the organization. We have to show courage and stand up for what is right. Reporter: Now he has resigned effective immediately. The family research council saying in a statement, we believe this is the best decision for josh and his family at this time. We'll be praying for everyone involved. The scandal could mark the end of what was looking to be a promising career in politics for josh Duggar. Devoutly pro life, he and his family are active in the anti-abortion movement. In my lifetime we are going to end abortion in the united States of America once and for all. Reporter: Campaigning for conservative candidates like Rick santorum. Rick is a man of great courage. And Mike Huckabee, current presidential candidate and former governor of Arkansas, the Duggar family's home state who came to josh's defense saying on Facebook, josh's actions when he was an under aged teen are as he described himself inexcusable but that Dunn mean unforgiveable. No purpose is served by those trying to discredit josh. It may be too late to save the family's TV show which has been on the air for ten seasons. I don't see a path for this family to come back from this. I don't see a path for redemption in the television world. It goes well beyond josh. The whole brand is destroyed by this. Reporter: Today, tlc, the network that made the duggars a household name announced they are pulling "19 kids and counting" off the air saying we are deeply saddened and troubled by this heart breaking situation and our thoughts and prayers are with the family and victims during this difficult time. Jim bob and Michelle said this is bringing the family closer to god and each other. When something like this happens within the family it can be very destructive and hopefully getting treatment, making an intervention and their faith help them to get through to the other side. Reporter: Celebrity can certainly pay the bills. It won't bury your problems. It's a reminder, as well, all that glitters on reality TV is not always gold.
