Yovanovitch seems like a good person who took her job seriously and was probably concerned that Russia invaded Ukraine and perplexed at our(America's) cowardly unwillingness to protect a victim country from Putin's dangerous aggression. I understand her concerns.
Shame on her for using insecure technology in the pursuit of her duties. Maybe there is a way to stop this from happening. If the Republicans and Democrats could ever stop pointing fingers at each other and work on a solution I imagine they could both find common ground. I suspect the old-farts in Congress are not experts and likely receptive to the advice of experts.
Both parties are telling me how much I should hate the other party...and I do.
