They can’t delay it. But its unlikely to happen before the new congress is seated. Time and political concerns.
Unless the Congress critters go on vacation thus a recess and then 0bummer cannot appoint her via recess appointment. If I am not mistaken. Thus she is in before the new Congress is seated. Either way they need to drag this out as long as possible because unless there is something overtly catastrophic in her background she is in.
Thanks!
