Local businesses across the US forwent income for the day to protest the Trump administration’s immigration crackdown and the fatal shooting of Renee Good and Alex Pretti by federal agents in Minneapolis.

In what was billed a “National Shutdown,” organizers called for a 24-hour general strike, asking students to skip school, business owners to close up shop, and consumers to refrain from spending for the day.

Some small and medium-sized businesses from coast to coast posted on their social media stating that they’d be closed on Friday as part of the demonstrations. Others said that they’d remain open to support their workers, but showed support for the protests.

Touchstone Climbing, a popular California-based climbing gym with about 20 locations, posted on social media that its gyms were closed and that hourly employees scheduled to work on Friday would be paid.

Medium, an online publishing company, told employees that they were free to take Friday off to participate in the protests.

Photos show crowds of demonstrators holding signs that said “ICE Out” and gathering in Los Angeles, Washington, DC, New York City, Boston, and Minneapolis, among other cities.

The protests come amid growing tensions in communities where the Trump administration has deployed federal agents. Many of the high-profile enforcement efforts have been concentrated in blue or so-called sanctuary cities.

In Minneapolis, two US residents, Good and Pretti, were fatally shot after a confrontation with federal agents that occurred within a span of a few weeks.

Hundreds of local businesses in Minnesota participated in an economic blackout last week, shuttering their stores for a day following the shootings. The Minneapolis Regional Labor Federation, which is tied to AFL-CIO, the largest labor union in the US, endorsed the general strike.

The Department of Justice announced on Friday that it opened a civil rights investigation into the shooting of Pretti, a 37-year-old registered nurse who was killed by a Border Patrol agent.

A minor, 2.4-magnitude earthquake struck in New Jersey on Friday, according to the United States Geological Survey.

The temblor happened at 3:42 p.m. Eastern about 4 miles northeast of Whitehouse Station, N.J., or about 35 miles west of Manhattan, data from the agency shows.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

One of two shooting deaths of U.S. citizens in Minneapolis by federal agents is the subject of a U.S. Department of Justice civil rights investigation.

The Civil Rights Division is investigating the Saturday killing of Alex Pretti, but not the shooting death earlier this month of Renee Macklin Good by federal agents in Minneapolis, Deputy Attorney General Todd Blanche said in Washington on Friday.

Pretti was shot multiple times Jan. 24 as Border Patrol officers tried to arrest him while he was recording immigration officers on his phone.

Blanche says the probe is separate from the U.S. Department of Homeland Security’s shooting investigation of the incident.

“It means talking to witnesses. It means looking at documentary evidence, sending subpoenas if you have to,” Blanche told reporters at a news briefing Friday on multiple topics. “And the Department of Justice, Civil Rights Division has the best experts in the world at this.”

Blanche gave no investigation timetable nor did he commit to the release of body camera footage of the agents. He said the department’s investigation would encompass events of that day as well as the days and weeks that preceded the Pretti shooting.

Under questioning, Blanche said the fatal shooting of Good isn’t receiving similar DOJ scrutiny.

“There are thousands, unfortunately, of law enforcement events every year where somebody is shot,” he said. “The Civil Rights Division of the Department of Justice does not investigate every one of those shootings. There has to be circumstances or facts, or maybe unknown facts, but certainly circumstances that warrant an investigation.”

Federal officials have excluded Minnesota investigators from assisting with reviews of both shootings, leading to a state lawsuit that seeks to require evidence of the Pretti shooting be maintained. State authorities haven’t ruled out bringing charges against federal officers after completing their own investigations.
