That's from June 7th, before the deployment of Marines. It only justifies the federalization of the National Guard, but as far as that goes, it appears to be a very reasonable interpretation of the law:
Whenever...the President is unable with the regular forces to execute the laws of the United States; the President may call into Federal service members and units of the National Guard of any State in such numbers as he considers necessary to ... execute those laws.
Notably, it doesn't say the governor has the right to refuse those "orders". If the governor had that right, they would be requests, not orders.
A very interesting article about this situation from a Georgetown law professor was posted somewhere deep in this discussion and is well worth reading.
The professor is strongly opposed to the deployment, and calls it "dangerous" and "pernicious" among other things. Nonetheless, he "thinks the federal government has both the constitutional and statutory authority to override local and state governments when it comes to law and order" and that "this [clause] is better understood as a purely administrative provision than it is as giving a substantive veto to the governor."
According to Governor Newsom he wasn't communicated with at all.
In an interview with All Things Considered host Juana Summers, Newsom said the mobilization order was not done with communication to or approval by his office. [1]
