INDIANAPOLIS (AP) _ Former Indiana schools chief Tony Bennett has asked the state's inspector general to investigate the Department of Education's actions during his tenure after resigning as Florida's education commissioner.
 
  Tony Bennett's request Thursday followed an Associated Press story showing that Bennett and his staff scrambled to overhaul Indiana's school accountability formula after learning a charter school founded by a top Republican donor had received a C. 
 
  Bennett has denied any wrongdoing and says the formula change wasn't directed solely at Christel House Academy.
 
  He resigned his Florida post Thursday, saying he didn't want the Indiana emails to distract from Florida's education efforts.
 
  His letter to Indiana Inspector General David Thomas calls emails cited in the story a “small snapshot of a long, arduous and iterative process'' of implementing Indiana's A-F grading.
