If the November midterm elections return Congress to Republican control, the new GOP leadership should take swift action to staunch the flood of illegal immigration loosed by President Joe Biden’s open border policies.

To protect the public and preserve our national sovereignty, it’s essential that the executive branch resume enforcing immigration law. That has not happened under Homeland Security Secretary Alejandro Mayorkas. A first step for the new Congress should be to demand his resignation. If he refuses, Congress should impeach him. However, more will need to be done to reverse what are unquestionably the worst U.S. border and immigration policies of modern times. The best blueprint for doing that was put together by a coalition of border security and immigration experts and published in an open letter two months ago.
