Careful what you ask for!
It would actually be no surprise if they extend her "report date" if prisons are refusing her. Federal prisons can be prima donnas and come up with reasons to reject somebody like SP -- not wanting another "high maintenance" inmate disrupting the mix! Naturally, this will be voiced in the context of rejection for "security" reasons. The last federal case I followed from Florida resulted in having to send the inmate to BOP Arizona.
I'm not kidding when I say the feds operate differently.
ETA: I don't recall how involved KP was with the bond/bail conditions SP was initially released on but they are still in effect until she is in federal custody behind bars. Obviously, KP and the children can't put SP behind them -- she's still a nasty thorn in his side.
