President Biden announced sweeping federal vaccine requirements today that include a mandate for all employers with more than 100 workers to require their employees to either get vaccinated or get tested weekly.
Biden is also signing an executive order to require all executive branch employees and contractors with the federal government to get vaccinated, without an option to get tested weekly instead.
All together, the new requirements could affect as many as 100 million people.
"We’ve been patient. But our patience is wearing thin, and your refusal has cost all of us," Biden said, speaking to approximately 80 million unvaccinated Americans.
