Chumney, an outspoken former city councilwoman and state representative who made a name for herself criticizing business-as-usual politicians, wrote a $30 check to the Firecracker 5K benefiting St. Jude Children's Research Hospital that was returned for insufficient funds.
"I just took care of that," Chumney said Monday morning. "Every once in a while it happens."
Chumney, a candidate in the upcoming special election to pick Mayor Willie Herenton's successor, said she has multiple checking accounts and funds from one account weren't transferred to the account used to write the check.
Chumney, 48, finished 12th in her division in the race.
