A House Democrat sent a letter to Education Commissioner Gerard Robinson Friday asking for an examination into an event hosted by Charter Schools USA that Gov. Rick Scott spoke at earlier this week. “It is unbelievable to think that one of the largest for-profit charter school organizations in Florida may have spent taxpayers’ money to bus thousands of teachers and executives to an Orlando pep rally attended by Governor Rick Scott and former Washington D.C. schools chancellor Michelle Rhee,” wrote Rep. Dwight Bullard, D-Miami. The letter asks for a full accounting of how the event was paid for. Scott, an advocate for charter schools, spoke at the pep rally-style event at Rosen Plaza Hotel on International Drive in Orlando. Thousands of Charter Schools USA employees were bused in for the event. Though Charter Schools USA is a for-profit company, its schools are paid for with tax dollars.
