When faced with the same request from Caesar, Cato used the device of filibuster, speaking continuously until nightfall, to prevent the senate from voting on the issue of whether or not Caesar would be allowed to stand for consul in absentia. Thus Caesar was forced to choose between a Triumph or a run for the consulship. Caesar chose to forgo the Triumph and entered Rome in time to register as a candidate in the 59 BC election, which he won. Caesar's consular colleague was Marcus Bibulus, the husband of Cato's daughter Porcia.
Cato did this with both Pompey and now Caesar.
