The widow of slain civil rights leader Medger Evers and evangelical Pastor Louie Giglio are scheduled to pray at president Obama's inauguration.

Myrlie Evers-Williams will give the invocation at the ceremony. Evers-Williams fought for justice for 30 years after her husband was gunned down in his driveway in 1963.

Rev. Louie Giglio of Atlanta's Passion Church will deliver the benediction at the end of the public ceremony.

Giglio hosts the annual New Year's Passion Conference and is an advocate for ending modern-day slavery.

The president said it was a privilege to have the two take part in the inaugural ceremony.

"Their voices have inspired many people across this great nation within the faith community and beyond," he said. "Their careers reflect the ideals that the vice president and I continue to pursue for all Americans - justice, equality, and opportunity."
