NEWT GINGRICH ABC News' Brian Ross and Rhonda Schwartz: " Exclusive: Gingrich Lacks Moral Character to Be President, Ex-Wife Says" Newt Gingrich lacks the moral character to serve as President, his second ex-wife Marianne told ABC News, saying his campaign positions on the sanctity of marriage and the importance of family values do not square with what she saw during their 18 years of marriage.  In her first television interview since the 1999 divorce, to be broadcast tonight on Nightline, Marianne Gingrich, a self-described conservative Republican, said she is coming forward now so voters can know what she knows about Gingrich.

ABC News' Chris Good and Elicia Dover: " Highlights From Newt Gingrich's 2010 Tax Returns" Newt Gingrich's tax returns aren't the flashiest or the most complicated, but the former House speaker pulled in quite a few dollars in 2010. Gingrich and his wife, Callista, made an adjusted gross income of $3,142,066 in 2010-most of it from one of Gingrich's companies, Gingrich Holdings, Inc., headquartered on K Street in downtown Washington, D.C.

The Hills' Justin Sink and Cameron Joseph: " Gingrich's attack on the media sets feisty tone for GOP debate" A fiery attack by Newt Gingrich on the news media for raising questions about his acrimonious divorce set the tone for a bruising Republican presidential debate that featured tough critiques of the presumptive front-runners - and more gaffes for Mitt Romney. Gingrich was pressed by moderator John King to comment about recent interviews given by Gingrich's second ex-wife, Marianne, in which she said that Gingrich had requested an open relationship. LINK
