"We want each speaker to come and give us their take on the gun violence issue and make this event a platform for those who different ideas about how to go about it because we know this issue is divisive," said Hiwad Haider, a student at San Jose's Prospect High School and one of the organizers.
With only a few hours to go, 21-year-old San Francisco State computer science student Ibraheem Chaudry continues to work on his speech for the march and rally in San Francisco. His goal is to capitalize on the momentum to change gun laws.
"This comes once in a lifetime, and it's of the essence to capitalize it at this moment and make sure everyone sees this through," said Chaudry at his family home in Foster City.

"A number of students from all across the Bay Area submitted videos, and that's how we were able to choose," said San Francisco lead organizer Dr. Shoshana Ungerleider. "We'll be hearing from age range 12 all the way up to 21 years of age."
In San Jose and in San Francisco, organizers have trained volunteers to handle security. They're being called global ambassadors. There will be others who will handle medical issues. Almost $40,000 has been raised to cover expenses in San Jose.
