On his return to Rome in 65 BC, Cato was elected to the position of quaestor. One of his first moves was to prosecute former quaestors for misusing funds and dishonesty. Cato also prosecuted Sulla's informers, who had acted as head-hunters during Sulla's dictatorship. Cato did this even when the men were well connected politically. At the end of the year, Cato stepped down from his quaestorship amid popular acclaim, but he never ceased to keep an eye on the treasury, always looking for irregularities.
