Sources report that a complaint has been lodged against Rep. Cynthia Davis (R-O'Fallon) alleging that Davis has not properly reported her Warren County billboard and questioning whether $5,280 paid to the Broadcast Center in St. Louis for education expenses was a personal (rather than campaign) expense. The complaint also alleges that Davis spent more on the training than advertised rates.
It's unclear how an expense for communications training would be deemed an inappropriate campaign expense, but you never know. Davis does have a record of paying personal taxes with campaign money.
We'll post more details as they're available.
