Capping off a week of festivities, President Barack Obama and First Lady Michelle Obama attended a prayer service on Tuesday morning (January 22) at the National Cathedral in Washington, D.C.

Joined by Vice President Joe Biden and his wife Dr. Jill Biden, the first couple greeted well-wishers as they made their way to the front of the historic church.

Impeccably dressed in a white suit, Mrs. Obama beamed at her husband as he received the accolades of the D.C. powerful who gathered to kick off his new term.

The service is the last official event of the inaugural festivities, a tradition that has been carried out by every president since Thomas Jefferson.
