A tax cheat is running the US Treasury. So far 13 other high level nominations have been withdrawn, mostly from failure to pay taxes.
The "Oops, I forgot to pay enough taxes" routine is getting pretty boring, I admit. It's not good.
Now to your flawed list.
Solis - confirmed. (oops!)
Sebelius - awaiting confirmation, not
Kirk - awaiting confirmation, probably today (oops!)
Freeman - derailed by AIPAC hit squad.
Gupta - withdrew because of pay cut.
Tierney - withdrawn. Deputy
Secy of Energy. Personal reasons.
Garvey - withdrawn. Reason not given.
Atkinson - withdrawn. Reason not given.
