Disgraced Theranos founder and CEO Elizabeth Holmes has quietly resigned from President Obama’s Presidential Ambassadors for Global Entrepreneurship advisory board.

The one-time high-flying Silicon Valley exec has seen plenty of bloodletting of late.

Holmes was accused last week at a scientific meeting of “baiting and switching” on a presentation. The conference was expecting to hear about the science behind the micro-blood test service; instead they got a demo on a prototype device to test cholesterol, white blood cell counts and the Zika virus, attendees complained.
