The Daily Mail reports Doug Emhoff - current husband of Kamala Harris - had an affair with his kids' nanny Najen Naylor and got her pregnant. This caused the breakup of his first marriage.
It may explain why he can live with the widely known fact his present wife was Willy Brown's side piece and protege'. Doug is no position to act "holier than thou" with Kamala.
A spiteful person might conclude they deserve each other. You might well think that, I couldn't possibly comment ... hat tip to the original British House of Cards for the tag line.
