MSNBC host Lawrence O’Donnell spoke out on Wednesday night to claim that Republican governors “are endangering children” by banning school districts from enacting mask mandates.

“There are 50 million children under 12 in the United States,” O’Donnell said. “All of those 50 million children now are unvaccinated, and like all unvaccinated people, those 50 million children need to protect themselves by wearing masks in public places indoors.”

“The Republican governors of Arizona, Arkansas, Florida, Iowa, Oklahoma, South Carolina, Tennessee, Texas, and Utah are endangering children by banning school districts from setting mask mandates, refusing to protect children as they return to their classrooms,” he added. “This week the Texas Supreme Court upheld Republican Governor Greg Abbott’s ban on mask mandates in schools.”

Not stopping there, O’Donnell proceeded to double down.

“Governor Abbott is now, as we speak, isolated after testing positive for the coronavirus. Governor Abbott is receiving monoclonal antibody treatment Regeneron, also used to treat Donald Trump. Ken Griffin is the CEO of a Chicago-based hedge fund that is heavily invested in Regeneron,” he said. “Ken Griffin is also a top financial contributor to Florida’s Governor Ron DeSantis. Nothing is better for the stock price of Regeneron than an increasing number of COVID-19 infections.”

“With COVID-19 infections on the rise in Florida, Governor DeSantis plans to open between 15 and 20 Regeneron treatment sites across the state that could offer 300 treatments per day,” O’Donnell continued. “Governor DeSantis spends little time trying to stop the spread of COVID-19 but is doing everything he can to spread the use of Regeneron for people in Florida infected by COVID-19.”

This came after DeSantis blasted Biden for his “obsession” with COVID-19 mandates.

“While you have all this stuff going on with Afghanistan, obviously all of the stuff at the southern border… one of the biggest border disasters in the history of our country, inflation, gas prices, and what does he do? He is obsessed with having the government force kindergarteners to wear masks all day in school,” DeSantis told Fox News.

“You got to wonder: Where are your priorities that you’re so obsessed with this issue and so obsessed with taking away parents’ rights?” he asked. “And you’re letting Afghanistan burn, our border burn and so many other things in our country fall to pieces.”
