It seems almost every day there is a polygamy scandal - the scandal is that people keep thinking the Mormon Church practices polygamy. The fact of the matter is that the Mormon Church - The Church of Jesus Christ of Latter-day Saints - stopped practicing polygamy 120 years ago in 1890.
When someone in the Church is found to be practicing polygamy, they are quietly excommunicated. There haven't been any high-profile cases or scandals regarding excommunication within the Church for polygamy since the early 1900's.
Polygamous groups who have been in the news somewhat recently are:
-The True and Living Church of the Saints of the Last Days (TLC): in the news 1998-2005 news regarding false predictions of the apolcalypse and a couple kidnapping their baby from a hospital.
-Tom Green Family: in the news 1999 - 2007 scandals regarding a prison sentence for child rape and bigamy
-Apostolic United Bretheren: 1998 -2010 no major scandals, in the news for holding pro-polygamy rallies in Utah
-Church of the Lamb of God (LeBaron Group): 2005-2010 scandals regarding murder
-Latter-day Church of Christ (Kingston Clan): 1998 - 2008 scandals regarding abuse and child custody
-Fundamentalist LDS (FLDS): 1998 - 2010 various allegations of rape and child abuse, invasion of Texas ranch

Are you referring to the Reorganized Church of Jesus Christ of Latter-day Saints, the Restoration Church of Jesus Christ of Latter-day Saints, or the Remnant Church of Jesus Christ of Latter-day Saints? The Reorganized Church of Jesus Christ of Latter-day Saints is the largest of the above, but changed its name to "Community of Christ" in 2001, and therefore is no longer referred to as "RLDS". They do not practice polygamy and often deny that Joseph Smith taught or practiced the doctrine. The Restoration Church of Jesus Christ of Latter-day Saints is a smaller group that broke off from the Community of Christ in 1991. They do not practice polygamy either. The Remnant Church of Jesus Christ of Latter-day Saints is another small group which broke off of the Community of Christ. Their origins are in the year 2000. They do not practice polygamy. Don't get the above confused with the Restoration Church of Jesus Christ, which broke off from the main body, the Church of Jesus Christ of Latter-day Saints. They are known for their open practice of homosexuality, and at least a handful of members are in openly homosexual polygamous relationships. It is the FLDS (Fundamentalist Church of Jesus Christ of Latter-day Saints), not the RLDS that is known for its practice of polygamy.
