I'm sure he will in the coming days. I think it's too early to give specifics until they can completely assess what's needed.
I was talking with my wife about this a few days ago. With the amount of aid that Texas, the rest of the Caribbean including Cuba and now Florida will need, donation fatigue will inevitably set in and become an issue, so any help will be good.
On the other hand, that is where exists massive corruption. As in You get XXX amount of dollars for aid but can only spend it with a specified handful of companies, which in turn give kickbacks all down the line, artificially inflating the cost of goods up to a factor of 10 times the actual value.
And to be clear, this practice exists just about everywhere in the Caribbean, not just in Cuba.
