A couple of things,  some have evidently forgotten; If any non citizens enters the United States illegally, it's illegal! Against the laws of the United States. Honestly that shouldn't be all that difficult to understand, ICE is the federal law enforcement agency of the United State's, its their duty to enforce the laws, remove those illegally in the country etc! President's have been using them to remove those who are referred to as illegals  for many years.  As a matter of fact they do this everyday, thats their job.              Here's a run down  that should ease your mind:

President Clinton *12.5 million Deportations

President George Bush Jr *10.3 million Deportations

President Obama *5.2 million Deportations

     Donald Trump 1.5 million Deportations and over 350 protest/riots                                                                                         one can deduce its purely political since there were no protests or riots under the previous   20 million deportations!

   * Numbers are estimates gather from many sources but are generally accepted!  

For some strange reason under President Biden there were around 11 (some claim it's closer to 20+) plus million illegal entries during his term in office?
