NASHVILLE, Tenn. -- Another legislative staffer is in trouble for sending an offensive e-mail from a state computer. This time, the aide's from a Democrat's office, and he's been fired.

Blake Graves worked for Rep. Karen Camper, a Democrat from Memphis.

House Speaker Kent Williams investigated claims that Graves used his state computer to send offensive e-mails about Asians and the disabled.

After that investigation was over, Williams decided to fire the employee.

Two days ago, an aide from Republican Sen. Diane Black's office was reprimanded for sending a racially-charged e-mail. Sherri Goforth said she's sorry about the message, which included photos of all the U.S. presidents. The photo of President Barack Obama showed two cartoon eyes in a black square.
