Sure, almost ALL of them have indeed worked here illegally and evaded taxes.
So why doesn't the "tough-talking" Trump also mention those people as not being the "good ones"?
He doesn't.
He certainly singles out the "rapists" and the "drug dealers" as not being the "good ones", which is great, but they are only a small minority of the 20 million illegals.
There are an estimated 2 million criminal aliens. From Trump's plan:
Mandatory return of all criminal aliens. The Obama Administration has released 76,000 aliens from its custody with criminal convictions since 2013 alone. All criminal aliens must be returned to their home countries, a process which can be aided by canceling any visas to foreign countries which will not accept their own criminals, and making it a separate and additional crime to commit an offense while here illegally.
