The Democratic leadership may be less than interested in investigating things that they failed to stop themselves.
As I've pointed out...several times...the Democrats on the intelligence committees enthusiastically endorsed these methods back then, and they don't want this looked at closely either.
The Left isn't going to get the "Bush perp walk" they've been hoping for, any more than they're going to get all the other left-wing fantasies that Obama was supposed to deliver five minutes into office.
