WASHINGTON -- A U.S. judge in Texas issued a nationwide injunction on Friday barring the federal government from enforcing President Joe Biden's requirement that federal workers without qualifying medical or religious exemptions be vaccinated for COVID-19. Judge Jeffrey Brown, who was appointed to the District Court for the Southern District of Texas by then-President Donald Trump, ruled that opponents of Biden's vaccination mandate for federal employees were likely to succeed at trial and blocked the government from enforcing the requirement.
