AS you even see here, those on the right have cooked up all kinds of identity of conspiracy theories about whistleblower and thy use these to say his/her identity is critical (as if one cannot analyze the cause of a fire without knowing who pulled the alarm)
well, even without the complaint there were alarms going off all around:
"But after traveling from Chisinau, Moldova, for two days of meetings and Ukrainian special-forces training observation in Kyiv and Berdychiv starting on Aug. 14, the staffers were shocked to learn from U.S. embassy officials that there was no new money coming into Ukraine, a congressional aide familiar with their trip told NBC News. The Trump administration had frozen military aid to the country in the midst of its war with Russia.
What's more, the two Appropriations staffers, Becky Leggieri and Hayden Milberg, couldn't even get an explanation for the holdup, because embassy officials didn't know the reason, the aide said. That set off a scramble in Washington to find out what happened to the hundreds of millions of taxpayer dollars that had been specifically earmarked by Congress for Ukraine and that now play a pivotal role in a mushrooming scandal that threatens to lead to the president's impeachment."
