The statue/drape issue: I researched this a couple of years back. I discovered that the drapes had been there through several administrations. A little further research led to my discovery that the drapes that had once been there were 'rented' specifically for press conferences. Someone in the Ashcroft team decided to save money and nix the rental agreement and purchase drapes outright. It took longer than expected to secure the purchase (which, having before been associated with government procurement, I can easily understand). Also, IMS, they ended up going back to the rental agreement as that ended up being cheaper in the long run.
I have no references whatsoever (anymore) so take this for what its worth.
Edit to add: I remember remarking at the time that if Ashcroft had a sense of humor he could have had a bit of fun with the press after it became a media focus. For the next press conference he could have had her decked out in a skimpy little French-maid outfit. Or maybe a ragged bathrobe, curlers and starkwhite nightcream covering her face. I guess that's why I'd be a poor fit for government service.
