The donation raises Kelly's personal contribution to more than $12 million in his bid to replace Jerry Brown as California's top law enforcement officer.
Kelly raised millions for his campaign by selling stock options he owned from Facebook, for which he worked as legal counsel and chief privacy officer for five years, ending in March.
Kelly has six opponents in Tuesday's Democratic primary: San Francisco District Attorney Kamala Harris; former Los Angeles City Attorney Rocky Delgadillo; Assemblymen Ted Lieu of Torrance, Pedro Nava of Santa Barbara, and Alberto Torrico of Newark; and employee rights attorney Mike Schmier.
