Marie Yovanovitch's testimony on Trump cracks the wall of silence

Ambassador’s decision to ignore state department gag and appear before the House committees will probably inspire others

No wonder the state department tried to stop Marie Yovanovitch from talking. The former ambassador’s written testimony to Congress expresses clearly and in the most solemn of settings, what growing numbers American diplomats have been feeling: that their institution is being left to rot.

It is too soon to say whether her evisceration of the state department delivered behind closed doors, will mark a turning point in Donald Trump’s struggle to hold on to his office. There will without doubt be a counter-attack.
