It appears that you have completely misread Sen. Howard's quote. Read it again for comprehension... he did not say that no children of foreigners would be citizens at birth. They will be, the only exception being the children of "foreigners, aliens, WHO BELONG TO THE FAMILIES OF AMBASSADORS or foreign ministers" assigned in the US. That is exactly what I and the 14th Amendment have told you. The only exception to jus soli, ever since colonial times, is the children born here to foreign diplomats. Howard's statement does not exclude children of foreign visitors or even illegal aliens if they are born on US soil.

This is of course how it always has been, and how every Supreme Court case on the issue has decided it. Trump and the GOP Congress cannot willy nilly change this.
