Elon Musk calling stay-at-home orders 'fascist' is the latest in a string of controversial comments over the past 2 months. Here's how the Tesla CEO has responded throughout the coronavirus crisis.

After Tesla posted surprise first-quarter profit on Wednesday, Musk said during a conference call that Tesla's forced factory shutdowns were a "serious risk" to its business.

"Frankly, I would call it forcible imprisoning of people in their homes against all of their constitutional rights, in my opinion," he said. "It's breaking people's freedoms in ways that are horrible and wrong and not why they came to America or built this country. What the f---. Excuse me. Outrage. Outrage."

Musk went on to say that while Tesla will weather the storm, other businesses will not, and that the shutdown is undemocratic.

"If somebody wants to stay in their house, that's great and they should be able to," he said. "But to say they cannot leave their house and that they will be arrested if they do, that's fascist. That is not democratic — this is not freedom. Give people back their goddamn freedom."

On Tuesday, CNBC reported that Tesla had scrapped its plans to bring employees back to work at its Fremont, California, plant after local officials extended orders that limit Tesla's ability to resume its full operations.

In multiple tweets on Wednesday, Musk praised the state of Texas for beginning to reopen its retailers, saying that businesses should "reopen with care & appropriate protection, but don't put everyone under de facto house arrest."

In another tweet, Musk said the government should "give people their freedom back." One post said simply, "FREE AMERICA NOW."

Musk's tweets sparked support from some of his followers, as well as backlash among doctors, tech workers, Musk fans, and Joan Grande, the mother of pop star Ariana Grande, who called Musk's comments "incredibly irresponsible" and called for a boycott of Tesla.

On April 16, CNN published a reporter that none of the 1,000 ventilators Musk had promised had been received by California hospitals, according to the governor's office. The news was first reported by the Sacramento Bee.

A spokesperson for the California governor's Office of Emergency Services told CNN at the time that "to date we have not heard of any hospital system that has received a ventilator directly from Tesla or Musk."

But Musk said the report was false, making a dig at CNN and tweeting at Newsom to "please fix this misunderstanding." Musk went on to say he had "receipts," sharing a screenshot of an email between a Tesla employee and a Los Angeles official that said the ventilators had been tested, and a note from a California-based hospital CEO thanking Tesla for delivering ventilators.

Musk also retweeted posts from multiple hospitals — though only one based in California — thanking him and Tesla delivering medical devices, then tweeted out a "partial list" of hospitals that had received ventilators.

The confusion may have resulted due to the type of machines Musk was delivering: Rather than the invasive ventilators used on severe COVID-19 patients, most of the devices Musk had sourced were noninvasive ventilators called BiPAP and CPAP machines, which are typically used to treat sleep apnea, but can be used on COVID-19 patients. CNN spoke with four hospitals on Musk's list, and all said they had received the latter type of device.

In late March, Musk replied to a Twitter user who asked for help for Louisiana's hospitals, which she said didn't have access to N95 masks, the respirator masks intended for healthcare workers.

"We'll try to get & deliver as many as possible," Musk said. "N95 masks are a pain to wear btw. Less onerous masks are better most of the time."

It's not clear who Musk was encouraging to use "less onerous masks," but if worn correctly, N95 masks can block out at least 95% of small airborne particles and are recommended for frontline medical workers dealing with COVID-19 patients by the Centers for Disease Control and Prevention.

While Musk seemed to say Tesla would try to send a shipment of them to Louisiana hospitals, he also seemed to be encouraging switching to a looser-fitting mask like surgical masks, which do not protect healthy people from acquiring the illness. (Surgical masks are typically used by surgeons to prevent spreading their own germs to patients.)

The CDC has since started advising that everyone wear some sort of cloth face covering when they go out in public to the grocery store or to pick up necessities.

At a news conference in late March, California Gov. Gavin Newsom announced that Elon Musk had delivered a shipment of ventilators to help California hospitals treat COVID-19 patients.

"China had an oversupply, so we bought 1255 FDA-approved ResMed, Philips & Medtronic ventilators on Friday night & airshipped them to LA," Musk later tweeted.

"If you want a free ventilator installed, please let us know!" he said, thanking Tesla's team in China, China's customs authority, and Los Angeles International Airport.

Newsom called Musk's efforts "heroic."

In several tweets in mid-March, Musk opened up about what happened when he contracted falciparum, a potentially fatal form of malaria that can affect the central nervous system or cause "acute respiratory distress," according to the Centers for Disease Control and Prevention.

Musk said at the time that he thought a drug that was used to treat his illness could be effective in treating the novel coronavirus.

"Had near fatal case of falciparum," Musk tweeted. "Would've died for sure if not for chloroquine. Doesn't mean it works for C19, but maybe better than nothing."

Doctors have been testing the effectiveness of chloroquine and a variant called hydroxychloroquine in treating COVID-19. There's currently no peer-reviewed clinical data proving the effectiveness of the drug and federal health agencies have advised caution in prescribing it.

Since Musk's tweets, the drug has become something of a household name. President Donald Trump became an advocate of the drug hydroxychloroquine as well, after he was reportedly told about it by Oracle cofounder and chief technology officer Larry Ellison, a close friend of Musk's.

Musk reiterated on Twitter in mid-March his stance that people were overreacting to the virus, saying that "the panic will cause more harm than the virus" in response to venture capitalist Jason Calacanis stating that the death rate was plateauing in Italy.

At the time, the COVID-19 death rate in Italy was continuing to rise at an exponential rate. Calacanis later acknowledged the error when someone pointed it out in response to his tweet.

Musk also stated that "kids are essentially immune" from the virus. Children represent a minority of confirmed cases, and some research suggests children and infants may be less susceptible to the virus than adults. But another study warns that there may be far more US children infected with the coronavirus than previously thought.

In a series of tweets in mid-March, Musk said Tesla and SpaceX factories already produced sophisticated components, and that making ventilators wouldn't be a challenge by comparison.

"Tesla makes cars with sophisticated HVAC systems," Musk tweeted. "SpaceX makes spacecraft with life support systems. Ventilators are not difficult, but cannot be produced instantly."

He tweeted again the next day, saying his companies were already working on the ventilators. Soon after, he vowed that Tesla's Buffalo, New York, plant would "reopen for ventilator production as soon as humanly possible."

"We're working on ventilators, even though I think there will not be a shortage by the time we can make enough to matter," Musk tweeted.

Musk's first comments on the virus came in early March with a brief tweet:

At the time, coronavirus cases had been recorded in 93 countries, more than 100,000 people had been infected, and more than 3,400 people had died from the virus. In the US, 240 cases had been reported and 14 people had died, including one in California, where Musk lives.
