American politician, author, and political consultant, Newton Leroy "Newt" Gingrich has an estimated net worth of $6.7 million Los Angeles Times. Newt Gingrich was the Speaker of the House of Representatives and one of the key leaders of the so-called Republican Revolution of the 1990s. A former professor of history at West Georgia College, Newt Gingrich was elected in 1979 to the U.S. House of Representatives. After a disappointing Republican showing in the 1998 election, Gingrich resigned the Speakership and his seat in Congress. Out of office, Newt Gingrich turned consultant, author and political pundit, and has been expert at keeping his name in the headlines despite not holding an elected position. He announced in May of 2011 that he was seeking the 2012 Republican nomination for president. The majority of this wealth comes “from a multimillion-dollar ‘promissory note’ from the Gingrich Group, LLC to Gingrich Productions, Inc., entities that are part of Gingrich’s eponymous network of nonprofit and for-profit organizations,” according to LA Times.
