Buffett said he attended the first graduation of the Small Business Program, which he credited to Goldman Sachs, at LaGuardia Community College about 10 years before he spoke in December 2020.

The claim is that Buffett attended the first graduation of the Goldman Sachs small business program (10,000 Small Businesses) at LaGuardia Community College, about 10 years before December 2020. True: news reports, Goldman Sachs or LaGuardia announcements, or event records show Buffett attended that program's first graduation at LaGuardia, and that the graduation took place in roughly 2008–2012. Mostly true: Buffett attended an early, though not the very first, graduation or a related LaGuardia program event in that window, or attended the first graduation but outside the 'about 10 years' window by a year or two. Mostly false: Buffett was involved with the program, for example as an adviser or speaker at another event, but there is evidence he did not attend a LaGuardia graduation. False: evidence shows he did not attend, or the program had no LaGuardia graduation of that kind.
