It is not today, that was from March 2016, during the presidential primary campaign.
Chelsea Clinton and Elizabeth Holmes did appear together at least twice for Hillary campaign fundraising, but in March 2016 not now. One event was in San Francisco and the 2nd was at a private home in Silicon Valley. Interestingly, they had initially announced the second event as taking place AT THERANOS.... then someone in the campaign had 2nd thoughts, obviously. So even two years ago Theranos was becoming toxic as politicians started to figure out that it might blow up in their faces.
