"I told you a few days ago that he was likely to have 1,000 ventilators this week," Newsom said at a Monday press conference, adding the ventilators arrived in Los Angeles and that Musk was working with the hospital association to get the equipment out. "It was a heroic effort."
Following Newsom's announcement, Musk tweeted about the delivery in further detail, noting the products came from China but were from FDA-approved companies.
Musk also thanked his Tesla team in China, the China Customs Authority and Los Angeles International Airport customs "for acting so swiftly."
Musk, who has received criticism for not taking the pandemic seriously enough, said last week that his companies were working on securing ventilators, but added he thought "they won't be needed."
The 48-year-old tech titan also recently said his companies would help make ventilators "if there is a shortage."

Separately on March 18, President Donald Trump announced he would invoke the Defense Production Act, one day after being asked if he would.
The Defense Production Act, enacted in September 1950 in response to the Korean War, ensures the private sector can ramp-up the manufacturing and distribution of emergency medical supplies and equipment.
However, at a March 20 press conference, there was some confusion as to whether Trump had officially asked American manufacturers to produce medical equipment, though Trump did specifically mention General Motors by name.
As of Tuesday morning, there have been more than 387,000 reported cases worldwide of COVID-19, including at least 46,450 in the U.S.
