It could all be a big lie, but I find it hard to imagine the utility of it.

Politicians get positive screen time and headlines acting like they care about 'transparency' in a context that won't effect them politically or their donors financially. They get to say a bunch of open-minded sounding but totally non-committal stuff about 'getting the public the answers they deserve' but they don't have to followup on anything. It's a bipartisan public brownie-points bonanza, plus it's a distraction from more controversial problems they should be addressing so of course they're going 'all-in'.
