I thought Jackie redid the WH.
You're absolutely right, she did! Another poster pointed out to me that they thought that there were two projects going on simultaneously, still another poster was nice enough to send me a site (post #59) that showed how the decorating project might look when completed.
I went back and reread the article with my original post about the million dollar renovation and I see that they mention the heating and cooling system. I'm wondering if that more expensive undertaking is to modernize the bones of the White House, the side that is involved with the more mundane day to day functions.
