Biden and Harris celebrate Kwanzaa in social media posts

The White House celebrated Kwanzaa in a pair of pre-recorded videos posted to Twitter on Monday, marking the seven-day non-denominational holiday aimed at honoring African Americans’ ancestral roots.

Kwanzaa is celebrated each year from December 26 to January 1, with a day dedicated to each of the Nguzo Saba, or seven principles. Celebrants light a kinara, or seven-pronged candle holder, for each principle: unity (umoja), self-determination (kujichagulia), collective responsibility (ujima), cooperative economics (ujamaa), purpose (nia), creativity (kuumba) and faith (imani).
