The Louisiana Democratic Party announced Friday that it has filed an ethics complaint against Sen. David Vitter (R-La.), saying he used town-hall meetings as campaign events because he criticized a Democratic House lawmaker. In a letter dated Thursday to the Senate Ethics Committee, Louisiana Democratic Party Chairman Christopher Whittington charged that Vitter used official resources to host two town-hall meetings this month, during which he disparaged Rep. Charlie Melancon (D-La.) and other Democratic Congressmen. The meetings took place in Melancons district. The House lawmaker could challenge Vitter for his Senate seat next year. Vitter spokesman Joel DiGrado dismissed the accusation, stating: The Democrats reaction to these town halls across America is to try to shut down the debate and suggest that its somehow out of bounds. Well its not out of bounds because this is still America.Instead of trying to shut down free speech, why doesnt Charlie Melancon have at least a single in-person town hall this month? he added. Sen. Vitter is having 19.
