Senator Cory Booker (D-NJ) was sworn into the U.S. Senate in 2013 and briefly ran for the Democratic presidential nomination in 2020. Long before either chapter, he was a college student in California, and later a graduate student in England, at the same time as a future LinkedIn co-founder named Reid Hoffman.
The two have stayed in each other's orbit ever since.
The Foundation
Booker and Hoffman attended both Stanford and Oxford together. Booker arrived at Stanford as a freshman in the late 1980s, when Hoffman was finishing his undergraduate degree, and the two later overlapped as graduate students at Oxford.
The Silicon Valley Bridge
Hoffman went on to help start PayPal and co-found LinkedIn, becoming one of the Bay Area's most active angel investors. As Booker built a national profile in Newark, Hoffman became an investor in Waywire, the online video startup Booker co-founded and chaired before his Senate run. Booker's stake in the company was valued at several million dollars at the time.
Still Writing Checks
Hoffman's political support has not tapered. He has contributed to Booker's Senate races and to Booker's 2020 presidential campaign, and he remains an active donor to Booker's campaigns as of 2025.
