I have no knowledge of this area of law, but responsible press are saying he can deploy NG and Marines to defend federal property and employees without anything special.
We tried that. Nothing has changed since then - if anything he has consolidated more power.
Republicans would have to lose a lot of seats for it to happen. Or, Trump would do something beyond the pale for the GOP. Hard to imagine what would make them change their minds on it. Probably not thousands of dead protesters.
I’d cite my source, but can’t find it. I also can’t find anything saying he is invoking it.
Do you have any specific source?
Edit: I’ve found several sources that make It clear the Insurrection Act had not been invoked.
