Is Kamala Harris Lying About Celebrating Kwanzaa as a Kid?

How many were celebrating Kwanzaa in the 1970's?

When I was growing up, Kwanzaa was a special time. Friends and family members would fill our home. We would listen to the elders tell stories and watch them light the candles on the kinara. During dinner, we would discuss the seven principles.
