ANNAPOLIS, Maryland — Republican Gov. Larry Hogan is blaming teachers unions for blocking students from returning to the classroom in Maryland’s largest public school districts after nearly a year of remote learning forced by the coronavirus.

Hogan is desperate for Maryland children to resume regular, in-person instruction, saying Wednesday he has satisfied key demands the teachers unions made as a condition for returning to campus. The governor invested $1 billion in federal money the state received to retrofit school buildings to address health concerns, provided 1 million coronavirus test kits to school districts, and moved teachers to the front of the line for COVID-19 vaccinations.
