COLUMBIA, S.C. (AP) - The governor of South Carolina is the latest state chief executive to receive a suspicious package in the mail.
Gov. Mark Sanford said Thursday that an envelope containing white powder was opened in his office. Officials said law enforcement and environmental investigators were on the scene.
One office in the Statehouse complex was evacuated.
Envelopes contained suspicious powder have been received this week by governor's offices in Alabama, Alaska, Hawaii, Maine, Michigan, Minnesota, Mississippi, Missouri, Montana, Oklahoma, Rhode Island and Texas.
Officials in some of those states said the powder was flour, corn starch or some other harmless food substance.
