US President Barack Obama holds up his fist as he walks back to the White House with First Lady Michelle Obama and their daughters Malia (R) and Sasha after attending a prayer service at the St. Johns Episcopal Church in Washington, DC, on October 11, 2009. St. John's was organized in 1815 to serve as a parish church for Episcopalians residing in neighborhoods in the west end of the District of Columbia. Beginning with James Madison, every U.S. President has attended service at the church. Pew 54 is the 'President's Pew.' AFP PHOTO/Jewel SAMAD (Photo credit should read JEWEL SAMAD/AFP/Getty Images)
