I’m pretty sure that the right to assembly and free speech is for everyone in our country. Citizen, illegal alien, vacationers, etc.
Although when one is an illegal alien, probably not the best idea to draw attention to yourself.
Hmm. Maybe we need to organize more of these rallies! “Are you an undocumented immigrant? Are you sick and tired of Trump? Join us next Saturday to hear lots of speakers, and we’ll have plenty of time for an open mike so we can hear from YOU - THE PEOPLE. Make sure you put your name and address on the sign up sheets to be notified of future events.”
