In 70 percent of op-eds written by Mitt Romney advisers, The Wall Street Journal failed to disclose the writer's connections to the Romney campaign, according to a Media Matters study. The Journal has published 23 op-eds in which a writer's Romney ties were not identified, and just 10 in which they were.

The Journal published a total of 23 op-eds from the following Romney advisers without disclosing their campaign ties: John Bolton; Max Boot; Lee A. Casey; Paula Dobriansky; Mary Ann Glendon; Glenn Hubbard; Michael Mukasey; Paul E. Peterson; David B. Rivkin Jr.; and Martin West. 

The Journal published a total of 10 op-eds from the following Romney advisers and disclosed their campaign ties: John Bolton; Martin Feldstein; Glenn Hubbard; William Kilberg; John Lehman; and Dan Senor.

In the case of John Bolton, the Journal disclosed he was advising Romney in an initial op-ed but failed to do so in subsequent op-eds. With regard to Hubbard, the paper failed to disclose his campaign ties in an initial op-ed but did do so in later pieces. 

Editorial page editors from across the country have criticized the Journal for a lack of transparency in its editorial pages, and several media outlets have noted their failure to disclose. Media Matters has also launched a petition urging the Journal to disclose the conflicts. The Journal has not responded to requests for comment from Media Matters and other news outlets about the paper's disclosure policies.

The Journal disclosed that Boot was advising Romney in a September 28 book review. Media Matters did not include book review pieces in our initial op-ed study -- which preceded the September 28 disclosure -- and in the total numbers for this study.
