"The 116th Congress is now seated. Well, sort of. Our government is shut down and very little is actually happening (arguably that has been true for quite some time). The garbage piles up, Congress approval rating sinks even further (down to 9% in a recent YouGov poll), and Donald Trump continues to astonish in his single-minded focus on building a wall that both conservative immigration experts and border patrol agents think is a very low priority on their immigration wish lists.
