Judge Karin Immergut’s ruling capped a dramatic weekend that included President Trump sending California National Guard members to Oregon and ordering others from Texas.
Federal judge blocks federalized guard from deploying to Oregon

Judge Immergut in Oregon v Trump now:

"I grant plaintiffs second motion for a TRO."

Federalized Texas and California Guard to Portland is a "DIRECT CONTRAVENTION" of court's TRO from Saturday.

Both on 12406 statute and Tenth Amendment grounds.
