President Barack Obama and first lady Michelle Obama are sending their prayers and best wishes to those celebrating Kwanzaa.

The Obamas say in a statement that the Kwanzaa celebration highlights the rich heritage of African Americans. They say families come together on Kwanzaa to reflect on the past year’s blessing and look forward to the promises that lie ahead next year. The Obamas are vacationing in Hawaii.

They’re calling attention to Kwanzaa’s seven principles, which include creativity, self-determination, purpose and unity, responsibility, cooperative economics and faith.

The Obama say they remain committed to building a nation that provides opportunity for everyone. They say there’s much to be thankful for as families light the Kinara, a candle holder used to celebrate Kwanzaa.

The seven-day African-American holiday starts Friday.

President Obama worked out at the Kaneohe Base Marine Corps Hawaii gym Friday morning around for about an hour.

Around 10:37 a.m., the President joined the First Family at the Bellows Air Force Station beach, according to the White House.
