Saving Social Security was not part of how he balanced the budget but it was an objective he outlined often as to why balancing the budget was a good thing to do and what we should do with the surplus.

President Bill Clinton achieved a federal budget surplus in the late 1990s by combining the Omnibus Budget Reconciliation Act of 1993, the Balanced Budget Act of 1997, and strong economic growth, while using the "Save Social Security First" initiative to propose dedicating projected surpluses to the Social Security trust fund

I mentioned it because we shouldn't be in the situation we're entering into (being unable to cover Social Security) because we had an easy way to cover the cost 2 decades ago. Younger generations, who will be taxed higher by the older demographics to cover their Social Security need to be aware of this so they get off their asses and vote.
