There's an amusing article with a headline to the effect "Trump promised a huge announcement. Then he started listing names." Just name after name, dozens upon dozens upon dozens, no explanation or context just a gigantic exercise in name-dropping.
As I hear it it serves a few political purposes. For one, tries to create a competing narrative about "We gotta open up the economy" to go against the epidemiologist argument that ending mitigation would cause nightmarish destruction, which, since there is no convenient group going saying just that, means it needs to be made, and who would be more likely and reliable to do such a thing than a bunch of industrial bigshots? Two, it gives the administration cover, which is very, very important to Trump (both politically and, I imagine, psychologically), as it then puts the onus for the success or failure of this policy onto them, or at the very least gives an easy accessible target for blameshifting. It's also a great way of just, you know, namedropping and making himself look good, which is as much of a necessity for a narcissist as breathing. "These people are advising me!"
It also is just a way of projecting himself as being in control and taking control back from the governors saying their unamerican governor things like "Trump does not tell us when to reopen the economy." Which is, I guess, another way to think about the council: Trump actually can't really force businesses to reopen any more than he can force states, but if he throws them into a council he might manage to bully at least some of them into it.
Now the main problem for Trump will be when this council gets together (If it gets together? It's unclear how exactly it's supposed to function either...) if they suggest, as many have in fields from banking to retail, that the focus should be fighting the virus...
