An unsubstantiated rumor on social media prompted the California Highway Patrol to release a statement regarding the issue Monday afternoon.
On Monday afternoon the CHP stated that they had been in recent contact with the Oregon State Police and had been reassured that the Oregon borders HAVE NOT been closed and that there are no current plans to close them.
If the situation should change, the Oregon State Police advised they would contact and coordinate with the CHP directly and updated information as will be shared as they receive it.
