A shelter for legal immigrants in South San Diego is gaining attention from anti-immigrant activists and local residents who have started a campaign of filming in front of the shelter and confronting the workers there, resulting in a police response on at least one occasion.

The shelter is called a "secret shelter" by the activists. One said the shelter is as part of a conspiracy by Sen. Bernie Sanders. “All these people are connected to Bernie Sanders,” says Amy Sutton in one of the videos she filmed from in front of the shelter. “Bernie is in the background. We have the proof."

In one video posted February 19, Melinda Oporto momentarily blocks the front gate of the shelter and prevents a security guard from closing it. Workers at the shelter then call the police, prompting Oporto to start screaming at the workers. "I can scream all I want! It's not illegal to scream!" She then starts chanting “traitors, traitors.” Oporto says to the shelter workers, "How does it feel to be a human trafficker? How does it feel to be an American traitor?"

The Southern Poverty Law Center, which tracks extremist groups in the U.S., identifies Oporto as a far-right activist.
