Her impeachment speech ( link ) was delivered July 25 1974 - yet here is a paragraph pulled out.
"Common sense would be revolted if we engaged upon this process for petty reasons. Congress has a lot to do: Appropriations, Tax Reform, Health Insurance, Campaign Finance Reform, Housing, Environmental Protection, Energy Sufficiency, Mass Transportation. Pettiness cannot be allowed to stand in the face of such overwhelming problems. So today we are not being petty. We are trying to be big, because the task we have before us is a big one."
