The event called the "Stop Family Separations" vigil turned into a rally in Santa Barbara Wednesday night.
About 400 participants showed up, honked horns and brought megaphones and signs.
One of the organizers said that President Trump's change of heart on the immigration and family separation issue didn't change their plans entirely.
Ralph Armbruster-Sandoval, a UCSB Chicano Studies professor, said that the President is still inflaming the public when he talks about immigrants.
Among those attending were former Congresswoman Lois Capps and Santa Barbara Mayor Cathy Murillo, who invited people to a Saturday morning meeting about the issue at the Trinity Episcopal Church.
She called for the humane treatment of undocumented families.
