The last time I can find him saying anything publicly about her, he said he wouldn't back her as CEO again - though he would back her as "chief science officer", before quickly changing the subject [2]. Again, he's clearly trying to show her some personal support as a friend and colleague when nobody else in the world will do that, whilst very clearly stopping short of endorsing or denying any criminal behaviour.
What can you find that's more damning than this?
And why is it so important to you that Tim Draper should have publicly trashed her? Is it not enough that basically every other media and investment figure in the world was trashing her? Do you not have anyone for whom you would publicly signal support, if they were at rock bottom and the rest of the world was piling onto them, even if you know they may have done the wrong thing?
