Considering the word "illegal" is in it, I would gander a guess that it's because of that word that Republicans think it should be a crime, or correctly stated, that Republicans state it's a crime. But don't take my word for it:

ilegal - Contrary to or forbidden by law, esp. criminal law

ilegal - forbidden by law or statute

ilegal - is used to describe something that is prohibited or not authorized by law or, more generally, by rules specific to a particular situation

ilegal - not according to or authorized by law : unlawful, illicit;

It is not republicans.  And they can think whatever they want.  The democrats passed the law (same as the republicans) and that MAKES it a crime and MAKES it illegal.  Wasserman "know nothing" Schultz is just too stupid to understand simple English - makes you wonder what the hell she is voting on in the House.

She looks stupid and sounds stupid but she is not. She is evil. The stupid ones are the people she is directing  her bullshit to. The illegal intruders are potential voters for the parasite party(democrats).

Given how she got the job, I am not sure she is not stupid as well - all Obama needed was a mouthpiece that did not use Mr. Teleprompter.

That doesn't seem to be working out too well!

Does it ever?  You do have to be stupid to be a liberal in the first place.
