The White House served notice this week that it would not cooperate with House Democrats’ impeachment inquiry in any way. And we’re starting to learn perhaps why.

Disclosures on Thursday suggest a White House that took very little care to separate official business from political and personal advantage and often circumvented established channels to benefit President Trump.

This isn’t exactly a revelation, but the speed of the new disclosures and the brazenness of the actions suggest there are plenty of people who bore witness to this and who could speak to it, if willing and/or allowed.

First, there was the news that political appointees overrode the career officials in the White House budget office to put a freeze on military aid to Ukraine. The career officials were reportedly concerned, and the political appointees didn’t provide a reason for the hold, which evidence suggests might have been withheld for political leverage on Ukraine to pursue Trump’s favored investigations.
