Ex-US Ambassador to Ukraine Marie Yovanovitch, says so. And she insisted, in her op-ed, that she and her colleagues had no obligations to her bosses:

When civil servants in the current administration saw senior officials taking actions they considered deeply wrong in regard to the nation of Ukraine, they refused to take part.

They, and she, also refused to resign. All of them simply presumed to disobedience and to a veto authority over their bosses’ instructions.

She went on:

We need to stand up for our values, defend our institutions, participate in civil society and support a free press.

Indeed. But in order for Yovanovitch and her fellows to do so, they need to consider the Progressive-Democrat mirror into which they stare, and to think about the Progressive-Democratic Party’s communications arm, our NLMSM masquerading itself as an independent press, for which Yovanovitch is writing her… apologia pro vita sua.

And this cri de coeur:

I have seen dictatorships around the world….

I suppose that, for a woman so timid she’s intimidated by an unfavorable job performance review, any government might look like a dictatorship.
