The letter was published on Facebook page of Leonid Kozhara, Ukraine's former Minister of Foreign Affairs. Kozhara copied the letter from the website news-front.info, which in turn got it from the website of hacker group cyberguerilla.org. The source said that the original file was allegedly received by the hacker group Anonymous.
The leaked document shows Washington's clear interference into the domestic issues of Ukraine. US Senators literally stand behind every decision that the Ukrainian Prime Minister makes. Washington doesn't merely advise Yatsenyuk, it makes decisions for him. The Prime Minister's job seems to be quite easy — to simply do as he's told.
In the letter, Durbin assured Yatseniuk that the US Senate was still behind him and was concerned by Poroshenko's recent removal of some key political figures.
"It is necessary to invest every effort to keep Oleksiy Pavlenko in his office of Minister of Agrarian Policy and Food. His discharge will create additional obstacles on the way of widening cooperation between the US and Ukrainian agricultural companies," the letter said.
At the same time, US Senators told Yatsenyuk not to appoint certain individuals to certain positions:
"Majority of the Senators agree that neither Mr. Demchyshyn, nor Mr. Kostyuk meets the job requirements."
