Disinformation is more than ever very likely. They had Tebow on the list and he tweeted out yesterday morning that was not the case. This whole list is nothing more than Trump letting the media sink itself by reporting assumptions as fact.
In reality, Sarah and Don have made their deal long ago and I fully expect that she will be first, Energy Secretary, long enough to shut it down, as she said she would, and then onto the consolidation of anything having to do with Interior, whether it is or not right now, being lumped in and dissected by getting rid of the waste and useless agencies.
