Former dog owner Gov. Kristi Noem (R-SD) has been nominated to be secretary of Homeland Security, a position for which she is totally unqualified and about which she knows nothing (except that it will get her out of South Dakota). You take what you can get. Fortunately, when former Trump campaign manager Corey Lewandowski sees a damsel in distress, gentleman that he is, he runs to the rescue. This may not have been a difficult call, given the large number of media reports that she is having an affair with him, despite being married to Bryan Noem for 32 years. If you want more on the scandal, look here, here, here, here, and here. The affair is apparently well known in South Dakota Republican circles.
One might wonder how Noem got a cabinet position for which she is completely unqualified. Yes, she pretends to be very Trumpy, but many Republicans pretend to be very Trumpy. Some reports say that Noem had a(n unnamed) dear "friend" close to Trump put in a good word for her. Another factor could be that Trump sees her total lack of law enforcement experience as a plus. This will allow Stephen Miller and Tom Homan to handle immigration and (forced) emigration without having her even involved. Then she can devote her time to learning about FEMA, the Secret Service, and other agencies. DHS is big. It has more employees than any department except DoD. She will have enough to do learning about what DHS does, even if immigration is on someone else's plate.
Lewandowski has been sitting in on meetings and "helping" her pick high-level personnel for her department. This will ensure that all her deputies and assistants will be sufficiently Trumpy and some of them may actually be capable of doing (part of) her work. When a reporter asked Lewandowski about his involvement with DHS, even though he has no formal role there, he said: "It's all fake news and no one cares." (V)
