No wall. Very few deportations. What is wrong?

There are way too many illegals in the United States and the country has let it way too many immigrants.  Now all you see are foreign-born people everywhere.  Huge numbers of Mexicans, Chinese, and now middle-easterners as well.

Donald Trump was elected to deport all illegals from the United States, to hold all employers who hire illegals responsible, to build the wall, and to stop (and hopefully reverse) immigration.

What is wrong?  Why isn’t this happening yet?  Every day that illegals are able to stay in the United States means more and more of them.  The situation needs to change drastically and quickly.
