A group of around 300 people gathered Thursday night in the Harvey Milk Plaza armed with signs reading “Mob for Bob,” “You can’t fire the truth” and “Nobody is above the law.”

Ostensibly, they had gathered because of the forced resignation of former Attorney General Jeff Sessions, in actuality, they had come to demand that special counsel Robert Mueller’s Russia investigation be allowed to go forward.

Jacqui Viale had known this day would come.

She had been signed up to host a “Nobody is Above the Law” protest in Long Beach for over a year, but she didn’t know exactly when it would happen. She’d been waiting for President Donald Trump to cross one of four “red lines”—including Mueller being fired or Deputy Attorney General Rod Rosenstein being replaced—before she and hundreds of other organizers across the country would have a “break glass moment,” triggering hundreds of protests.

“When Sessions was fired—and there’s no getting around it, he was fired—and then he took Rosenstein out as the next person in line, we knew that was a line he crossed because we knew he was trying to thwart the investigation,” Viale said.

She and the nearly 300 protesters at Harvey Milk Plaza were reassured by Long Beach Congressman Alan Lowenthal, who made a surprise visit to the protest, that Congress would ensure they would protect the investigation.

“We’re on the verge of a Constitutional crisis at this moment,” Lowenthal said. “This is unacceptable and inappropriate and unconstitutional. And you’re right, Congress has to take action.”

He promised that the new Congress taking power in January would “stop President Trump.”

For many protesters, they were worried the resignation of Sessions was a foreshadowing of things to come.

Andrew Virtue, a Long Beach resident, was holding a sign reading “1984” in reference to the George Orwell novel, he said, because “I feel like that’s the times were living in now. The fact that the White House of the United States of America is disseminating doctored video of Jim Acosta is astonishing. The White House is feeding us fake information and telling us it’s true and that’s what really disturbs me.”

Hours after the midterm elections handed the Democrats the House of Representatives, President Trump forced Sessions to resign as Attorney General on Wednesday.

Within 24 hours, activists from Move On had organized protests nationwide.

Viale said the protesters are worried Trump will be able to snuff out the investigation because he installed former Sessions chief of staff Matthew Whitaker, who many view as an ally of President Donald Trump and an outspoken critic of the investigation, as acting attorney general.

“We’re demanding that Whitaker be removed or recused himself and want our representatives to stand up like they’ve never stood up before,” Viale said.
