Trump will be vising California for sure this Tuesday, March 13th. He's gonna be examining he's silly border walls near San Diego and possibly visit the LA area. A such, be prepared for protests wherever he may go. Hopefully, not downtown; the traffic nightmares.
The LAPD says it's already ready for protests, via LA Times. Not the friendliest start to news of the President coming, but it's not like it hasn't be known he isn't well liked by the majority of Californians and the people of LA.
