So, Trump is to nullify the legal right of California to set it's own, stricter, standards for auto emissions?

Why exactly?  Because he could.  Or so he thinks.  Another juvenile, "so there" move by Trump. 

This Trump effort was By The Way . . . opposed by the industry manufacturers foreign and domestic.

NOBODY wanted this but Trump.   The stench of Fascism lingers in the air.

Another NuckenFutz idea from the Trump Circus.
