ELK GROVE VILLAGE, Il. — President Joe Biden is championing the fight against COVID-19, requiring workplace vaccination requirements to force the roughly 67 million unvaccinated American adults to roll up their sleeves.

Biden is delivering that message in Illinois, where he’s visiting a suburban Chicago construction site run by a company that’s imposing a new vaccinate-or-test requirement.

In the coming weeks, more than 100 million Americans will be subject to vaccine requirements ordered by Biden. The majority of the nation is already vaccinated and industry leaders mostly agree with the mandates for the safety of workers and the economy.

Biden also planned to meet with the CEO of United Airlines, Scott Kirby, whose company successfully implemented a vaccine mandate, with no option for workers to be tested. Less than 1% have failed to comply and risk termination.
