The reason why the Obama’s can’t stay at The White House guest house: John Howard.

Bloomberg journalist Margaret Carlson revealed that when the White House turned down Obama’s request in early December, it had not yet even invited Howard to stay at the Blair House:
I reported… on December 11 and 12 that there were no foreign dignitaries booked into Blair House during that period of time… I have the feeling they asked him [Howard] to come and stay so that there might be some plausible reason for not letting the Obamas stay there.
