Emhoff, a lawyer, had been married before, to film producer Kerstin Emhoff. The couple shares two children, Cole and Ella, and divorced after 16 years of marriage.
Harris was serving as California's Attorney General.
The two were set up on a blind date by Harris' friend Chrisette Hudlin, who met Emhoff through work.
"The morning after our first date, @DouglasEmhoff emailed me a list of his available dates for the next couple of months," Harris wrote on Instagram on Emhoff's birthday in 2020. "He said, 'I want to see if we can make this work.' We've been making it work ever since."
Emhoff described meeting Harris as "love at first sight" in an Instagram post for her birthday.
