The personal financial disclosures incumbent members of Congress are required to file every year offer a rare insight into the way elected officials make, and spend, their money. This year, we couldn't help but notice a few interesting line-items, including wedding gifts, book advances -- and one senator whose stock portfolio is a virtual battleground in the Cola Wars.
-- Sen. Thad Cochran, R-Miss.: Cochran sold stock holdings in PepsiCo in 2012. Then he bought Coca-Cola stock.
-- Sen. Susan Collins, R-Maine: Collins was married last year to GOP consultant Thomas Daffron, and the happy couple received some nice gifts. Former Sens. Bob and Elizabeth Dole gave the newlyweds a $400 silver serving dish (Daffron managed Elizabeth Dole's 2000 presidential campaign). Former Defense Secretary William Cohen, whose Senate seat Collins now holds, gave the bride and groom a $595 vase.
-- Former Sen. Jim DeMint, R-S.C.: DeMint resigned earlier this year to take the top job at the conservative Heritage Foundation, but he still had to declare a $28,333 book advance from Hachette Publishing.
-- Sen. Marco Rubio, R-Fla.: Rubio earned $800,000 in book royalties from the Penguin Group. His book, "An American Son: A Memoir," was released last June. Sentinel, Rubio's publisher, is "a dedicated conservative imprint within Penguin Group."
-- Sen. Bernie Sanders, I-Vt.: Sanders isn't doing as well as Rubio. He earned around $5,000 in royalties for "The Speech," a published version of his 2010 filibuster against a deal to extend the Bush tax cuts. "The Speech" currently retails for $3.26 on Amazon.com.
-- Sen. Kirsten Gillibrand, D-N.Y.: Gillibrand sold a "vacant lot" in Mt. Merion, N.Y., for somewhere between $100,000 and $250,000.
-- Sen. Johnny Isakson, R-Ga.,: Isakson reported a net worth of between $6 million and $17.7 million in 2011, but he and his wife took in $43,344 in Social Security benefits in 2012.
-- Sen. Mark Pryor, D-Ark.: Pryor only holds two significant assets, according to his disclosure form: An account held with OneBanc in Arkansas worth between $1,001 and $15,000, and a second OneBanc account in D.C., worth less than $1,000. Pryor earned less than $201 is interest, his form shows.
-- Sen. David Vitter, R-La.: Vitter reported a $32,210 salary from the Archdiocese of New Orleans. Vitter's wife has worked for the church in the past, but the salary isn't listed as belonging to his spouse.
-- Sen. Thomas Carper, D-Del.: Carper, a former governor and state treasurer, earned just under $34,000 from his state pension in 2012. (National Journal's Shane Goldmacher reported last week that Sen. John Cornyn, R-Texas, has three public pensions, which altogether totaled more than $65,000 last year.)
Not all senators have filed their disclosures, of course. Sens. Chuck Schumer, D-N.Y., and Dick Durbin, D-Ill., have filed extensions, for example.
