The Trump and Giuliani allies driving the attempt to change the senior management at Naftogazt, however, appear to have had inside knowledge of the U.S. government's plans in Ukraine. For example, they told people that Trump would replace the U.S. ambassador there months before she was actually recalled to Washington, according to three of the individuals interviewed by the AP. One of the individuals said he was so concerned by the whole affair that he reported it to a U.S. Embassy official in Ukraine months ago.
