My theory/fantasy is that Nielsen resigned so suddenly because POTUS was able to share his plans for the border with her when they visited the Wall together this week. He probably told her in person and she didnt want to be part of whats coming in the next month.
Good news for border security? I hope so.
I like that idea.
I think it’s good news because he’s replacing her with the current head of Customs and Border Protection. Like, CPB not getting what they want from the seventh floor of DHS? Make the CPB guy head of DHS. Smooth move. Only concern is the Obama people seemed to like him.
