Ambassador Mulford has no business to behave not like an Ambassador. An Ambassador has to behave under certain norms.
The US Ambassador does not seem to understand how to behave as an ambassador in this country. An ambassador has to behave according to certain norms.
I can understand an American Senator or a Congressman making some comment. Even I can go to the US and make some criticism. I have no problem with that. But an ambassador has to behave according to certain norms.
