Don't believe me. Believe Democratic Senator Richard Blumenthal of Connecticut. After all, it was Blumenthal who was scholarly enough to remind us at the Kavanaugh hearings of the importance of that apothegm of Roman law "falsus in uno falsus in omnibus" (false in one thing, false in everything).
It's no great stretch to say that by allowing people to enter our country "undocumented" (i. e. break the law), Democrats are simply telling them the laws of our country don't really count. They are to be winked at or broken.
