There are ways to avoid senate interference entirely.
The simplist is to use a Partisan when capturing an enemy city. This way no talks are immediately initiated from the AI. Then, you go through your embassy and choose to talk to that civ. They will yell at you and that's it. No Senate interaction at all.
This is known as the Emissary's Ploy.
