On the Agrarian Law (2.24-2.25)

Therefore, an exception is made by this law, mentioning not youth, nor any legal impediment, nor any command or magistracy, which might be encumbered with obstacles arising either from the business with which it was already loaded, or from the laws. There is not even an exception made in the case of any convicted person, to prevent his being made a decemvir. Cnaeus Pompeius is excepted and disabled from being elected a colleague of Publius Rullus (for I say nothing of the rest). For he has worded the law so that only those who are present can stand for the office; a clause which was never yet found in any other law, not even in the laws concerning those magistrates who are periodically elected. But this clause was inserted, in order that if the law passed you might not be able to give him a colleague who would be a guardian over him, and a check upon his covetousness.

Did you think, otherwise, that when a few men had cast the eyes of covetousness on all your possessions, they would not in the very first place take care that Cnaeus Pompeius should be removed from all power of protecting your liberty, from all power to promote, from all commission to watch over, and from all means of protecting your interests? They saw, and they see still, that if, through your own imprudence and my negligence, you adopt this law, without understanding its effect, you would afterwards, when you were creating decemvirs, think it expedient to oppose Cnaeus Pompeius as your defence against all defects and wickednesses in the law. And is this a slight argument to you, that these are men by whom dominion and power over everything is sought, when you see that he, whom they see will surely be the protector of your liberty, is the only one to whom that dignity is denied?
