See this latest piece shared by Claire Rubin, A workable Homeland Security plan for Trump, where there is nary a word about a topic near and dear to my heart. It is all about the border, the border and then of course, the border.
It should not be surprising that when local elected officials delegate emergency management duties to a department head as an ancillary duty that the same thinking trickles up the chain to the national level. If I was to make the case for FEMA to be a separate cabinet agency, this is one of the points I'd make. When you look at the cost of disasters, and anticipation of increasing costs, you can see the financial hit to the federal budget.
Emergency management will never be a primary duty for the secretary of DHS. It is an additional duty, just like it is for the fire chief.
