Followed Trump's orders on pressuring Ukraine, says senior US diplomat

The ambassador testified that he told Vice President Mike Pence in September that US security aid to Ukraine had been stalled apparently because of Trump's demand for the investigations

A senior US diplomat told lawmakers on Wednesday that President Donald Trump expressly ordered him and others to help pressure Ukraine into investigating a political rival of the president, providing some of the most significant testimony to date in the House of Representatives impeachment inquiry.
 
In remarks that also put Secretary of State Mike Pompeo at the center of the Ukraine controversy, US Ambassador to the European Union Gordon Sondland said Pompeo was “fully supportive” of the efforts to push Ukraine into carrying out two investigations that would benefit Trump politically at home.
