1/ A federal judge in Florida struck down the Biden administration’s Covid-19 mask mandate for public transportation. U.S. District Judge Kathryn Kimball Mizelle, a Trump appointee, said the CDC exceeded its authority and had incorrectly claimed the mask mandate was a form of “sanitation.” Mizelle wrote that “Wearing a mask cleans nothing. At most, it traps virus droplets. But it neither ‘sanitizes’ the person wearing the mask or ‘sanitizes’ the conveyance.” The White House, meanwhile, said the CDC continues to recommend that people wear masks on public transportation and that the Justice Department will determine whether it will appeal the ruling.

3/ Alex Jones’s Infowars filed for bankruptcy in an effort to settle defamation lawsuits over his comments that the Sandy Hook Elementary School shooting was a hoax. Jones and his companies last year were found liable in a defamation lawsuit brought by the relatives of the 20 children and six teachers who were killed in the 2012 shooting. Jones called the massacre a hoax and that crisis actors faked the shooting in an effort by the government to take away guns and restrict firearms. The bankruptcy filing puts civil litigation on hold while the business reorganizes its finances. (NPR / Associated Press / Reuters / Bloomberg)
