By way of a working from home Twitter message, Apple CEO Tim Cook announced that the company has sourced and will be donating 10 million face masks. The number is a sizable increase over the two million reported last week, and a hefty bump over the nine million figure Vice President Mike Pence announced during last night’s White House press conference.

“Apple has sourced, procured and is donating 10 million masks to the medical community in the United States,” Cook says in the video. “These people deserve our debt of gratitude for all of the work they’re doing on the front lines.”

Proud to share we’ve been able to source 10M masks for the US and millions more for the hardest hit regions in Europe. Our ops teams are helping to find and purchase masks from our supply chain in coordination with governments around the world. pic.twitter.com/uTsA6eA5ks — Tim Cook (@tim_cook) March 25, 2020

Apple is joining fellow tech companies in donating masks amid a national shortage as COVID-19 takes an increasing toll on the U.S. population. Many of the donated masks have been stockpiled, in order to adhere to California Occupational Safety and Health Standards put into action following last year’s devastating wildfires.

Other companies, like Ford, have transformed production facilities to create additional masks.
