The only reason the president should be able to claim a national emergency is if and when there is a sizable emergency, hurricane Katrina with all the fires could have been a national emergency many states were effected. An emergency is when very large numbers of people are affected. There is a drug problem, trafficking problem, and an immigration problem; but they aren’t all totally in the area of where the wall will be. There is a worse immigration problem with those flying in to the US. More drugs are coming in by ship. Trafficking is all over. I will admit the problems that come across the Mexican/American border isn’t under control, but it’s not a national emergency, more help is needed, but not a wall. Trained people with trained dogs would do more good than a wall.
