That’s a fair point. I was under the assumption that they were still using the “invasion” thing since that was what they leaned into for the deportations. I can definitely see them going with “rebellion” instead.

Seems like there is some (temporary) good news on the topic at least:

A federal judge issued a temporary restraining order Thursday directing President Donald Trump to return control of the National Guard to California.

The order, which takes effect at noon Friday, said the deployment of the Guard was illegal and both violated the Tenth Amendment and exceeded Trump’s statutory authority.

I appreciate you being upfront about your source, lol. Here’s some info from AP News to help clarify a bit.

Typically the authority to call up the National Guard lies with governors, but there are limited circumstances under which the president can deploy those troops. Trump federalized members of the California National Guard under an authority known as Title 10.

The relevant part of Title 10 is explained here: https://www.law.cornell.edu/uscode/text/10/12406

Which basically says that the federal government can deploy the National Guard when

the United States […] is invaded or is in danger of invasion by a foreign nation

So Trump is (falsely) claiming that the protesters are helping Mexico/Venezuela/Wherever to “invade” California. Which is obviously complete horseshit, but unfortunately that same excuse has been working for his other fascist orders such as the deportations to CECOT.
