That bitch should be facing a firing squad. She was involved in the organization and funding of the 2014 coup and then decided on who should be in the cabinet of Ukraine, The only qualification for her pick was hatred of Russia. That being the case the Russian Speaking people were under threat and as a result the Civil; War started, She promised to introduce some of her choices to Biden.
In any event her next sin was even worse. When Putin submitted proof of the existence of bio-labs in Ukraine. she denied it and so did her bosses and Biden. That denial was followed by a lorry-load of BS, The new claim was that there are bio-labs b uilt in the Soviet era and that the USA are helping the Ukrainians to close down the bio-labs. That one was to cover up the existence of the bio-labs somehow - very clumsily done and not working. Expected more from her than the low lying routine by her.
Then the inevitable happened - she was asked by Senator Rubio whilst under oath - about bio-labs in Ukraine - she she gave three answers under oath:-
* She said there are bio-labs in Ukraine;- according to Tulsi Gabbard there are 26 Bio-labs in Ukraine
* the bio-labs are not involved in dangerous research;
* the US Government is worried about the Russians getting hold of the pathogens - it must be added that when the Russians did enter three labs - they found written instructions from Washington about destruction of the pathogens and documentation as well.
* that any bio-lab leakage will be done by the Russians
So this woman was closely involved in the start of the civil war in Eastern Ukraine that ended up in a full-scale war. The victims of her approach must be numbered in the hundreds of thousand by now.
Why is she resigning now? I think she wants to be out of sight when Biden is out of the WH and the lies get further exposed. She is and remain a liar and a very dangerous and murderous individual. .
