In President Joe Biden's Thursday address he'll announce that all businesses with 100 or more employees must require vaccinations or weekly testing. Businesses that don't comply could be fined, according to a senior administration official.
“The new vaccination requirements in the president's plan cover about 100 million workers -- that's two-thirds of all workers in the United States,” a senior administration official said on a briefing call with reporters Thursday afternoon.
Biden's also looking to make testing more accessible and affordable. Walmart, Amazon and Kroger will sell at-home rapid tests at-cost for the next three months, meaning the price will drop about 35%.
The mask mandate for interstate travel and on federal property will stay in place through Jan. 18 2022, and the fine for violations will be doubled, the official said.
Biden will address the public at 5 p.m. ET.
