Wikipedia has certain policies that must be followed, including the maintenance of a neutral point of view and the use of reliable sources. It's true that the article as written is not very well-sourced and needs major improvement, but the material that's currently here is not actually controversial — it's not really much more than a thinly veiled rewrite of her résumé. That isn't particularly good content, granted, but it's not factually in question and it doesn't fail NPOV.  

 The stuff about FATCA, however, is attempting to advance an ideological position and is being sourced to bad, unreliable and/or primary sources — and thus I have to direct you to the WP:BLP notice at the very top of this page, which explicitly states that Unsourced or poorly sourced contentious material about living persons must be removed immediately from the article and its talk page, especially if potentially libellous. 

 A properly written, properly sourced and neutral summary of her role in FATCA would be perfectly acceptable content in this article. What's actually been added so far, however, is none of those three things.
