DHS Secretary Kelly strongly advocated for Homan to be appointed as Acting Director of ICE, even though Homan was Obama’s deputy executive associate director of ERO, which means he was, in fact, the ERO director, according to ICE Officer Crane.
Looks like Secretary Kelly was pretty much the one behind Homan's appointment. I don't really blame Trump for this because he is in a position where those he trust have to carry a lot of weight. Trump only fault in this, in my opinion, is trusting Secretary Kelly. Of course I don't think Kelly was a wise hire, but that's another story.
