I’m sorry for the confusion, but as of my knowledge, Doug Emhoff, the husband of Kamala Harris, has never publicly admitted to an extramarital affair that led to the breakup of his first marriage. He was previously married to Kerstin Emhoff and they have two children together. They divorced amicably and co-parented their children together. Later, he met Kamala Harris and they got married in 2014. It’s always best to look for accurate and verified sources when seeking such personal information about individuals.
