The list consists of CEOs of many companies from different states and senators. Since each state is impacted differently and some are in better/worse situation than others, every company's opinion matters. There are also CEOs/business people from different venues like restaurants, NBA, NFL, UFC, Disney and other parks, bars etc. I think 200 might be too low. 200 divided by 50 states is around 4 per state.
Ah, yes,here we go, 200+ people: https://www.axios.com/white-house-reopen-america-task-fore-8...
(Which means it's a no-op. No group of 200 people is able to move at any kind of speed)
