One would think that you guys would understand by now that Trump tweeting about something is not to be taken as an implication that anything will actually happen.
The Posse Comitatus Act would be a difficult hurdle to overcome.
The PURPOSE of the military is national defense e.g. US borders. This has nothing to do with Posse Comitatus.
Of course it does. Barring exceptional circumstances, the Posse Comitatus Act prohibits the deployment of US military on US soil.
And again...It does not include the Army or Air National Guard.
It prohibits using combat troops for domestic situations. Guarding the
American border from an invasion is NOT a domestic situation.
But it is all irrelevent if he uses the National Guard. (Army and Air)
He can deploy the Guard and stop the "invaders" in their tracks.
Only with the permission of the States he's borrowing the guard from, or by declaring a national emergency.
So he calls Abbott in Austin and tells him to send in the Guard. You
think Abbott would refuse? I don't.
Declaring a National Emergency is the easy way to go. He then puts the
Guard under Federal Control and away from the States.
During the riots of the 60's there were numerous times when Federal
Troops were ordered in by the President to return law and order.
Ike did it in Little Rock in the 50's when he sent in the 101st Airborne.
The riots by Vets was met by MacArthur and Federal Troops in Washington
DC in the 20's or 30's.
Trump, btw, is now saying he will put the Military on the border to guard it
until the wall is built. He is not deploying combat troops on American soil
he is using troops to guard our International Borders, which are only controlled
by the Fed govt. not the States.
He is upping the ante to protect the border.
