Hough was born in Orem, Utah, the youngest of five children in a Latter-day Saints (Mormon) family. Her parents are Marianne and Bruce Hough; her father was twice chairman of the Utah Republican Party. Her brother, Derek Hough, is also a professional dancer. She also has three older sisters: Sharee, Marabeth and Katherine.
Hough was one of the Million Dollar Dancers in the 2006 ABC game show called Show Me the Money. She won season four of the U.S. edition of Dancing with the Stars with her partner Olympic gold medal-winning speed skater Apolo Ohno, making Hough the youngest professional dancer to win on the program. On November 27, 2007, Hough and her partner, three-time Indianapolis 500 champion Helio Castroneves, became the winners of season five. Hough returned for season six with radio host/comedian Adam Carolla, but they were eliminated in week four. In July 2008, Hough was nominated at the 60th Primetime Emmy Awards in the category of "Outstanding Choreography" for her Mambo "Para Los Rumberos" (performed with partner Helio Castroneves) on Dancing with the Stars. On August 25, 2008, the cast of season seven was announced, and Hough was partnered with Hannah Montana actor Cody Linley. She felt abdominal pains during their jitterbug performance on October 27, 2008 and was immediately rushed to a hospital following the encore performance. She subsequently had surgery to have her appendix removed, causing her to miss several performances; Edyta Sliwinska stood in for her. Hough returned to the show, although the pair was ultimately eliminated in the Semifinals Competition. She appeared on the November 12 results show dancing the jive to "Great Balls of Fire" with her brother for the "Design-A-Dance" contest. On November 20, 2008, Hough told Ryan Seacrest on his radio show she would not be returning to Dancing with the Stars, for the foreseeable future, in order to further her music career. However, she did return for season eight, partnering with boyfriend at the time, country singer Chuck Wicks. They were voted off in week eight of the competition and came in sixth place. On October 11, 2011, Hough returned to Dancing with the Stars and danced with her Footloose co-star Kenny Wormald twice, as well as her brother. She returned again on May 15, 2012 in a dance performance to promote her film Rock of Ages. On October 7, 2013, she was guest judge in place of Len Goodman, which was the first time a former pro dancer came back to judge. In September 2014, she returned as the show's permanent fourth judge.

James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
In March 1860, the House created the Covode Committee to investigate the administration for evidence of offenses, some impeachable, such as bribery and extortion of representatives in exchange for their votes. The committee, with three Republicans and two Democrats, was accused by Buchanan's supporters of being nakedly partisan; they also charged its chairman, Republican Rep. John Covode, with acting on a personal grudge (since the president had vetoed a bill that was fashioned as a land grant for new agricultural colleges, but was designed to benefit Covode's railroad company). However, the Democratic committee members, as well as Democratic witnesses, were equally enthusiastic in their pursuit of Buchanan, and as pointed in their condemnations, as the Republicans. The committee was unable to establish grounds for impeaching Buchanan; however, the majority report issued on June 17 exposed corruption and abuse of power among members of his cabinet, as well as allegations (if not impeachable evidence) from the Republican members of the Committee, that Buchanan had attempted to bribe members of Congress in connection with the Lecompton constitution. (The Democratic report, issued separately the same day, pointed out that evidence was scarce, but did not refute the allegations; one of the Democratic members, Rep. James Robinson, stated publicly that he agreed with the Republican report even though he did not sign it.) Buchanan claimed to have "passed triumphantly through this ordeal" with complete vindication. Nonetheless, Republican operatives distributed thousands of copies of the Covode Committee report throughout the nation as campaign material in that year's presidential election.
