Des Moines, Iowa (CNN) Eric Holder, the nation's first African American attorney general and a longtime confidant to President Barack Obama, endorsed Hillary Clinton on Wednesday in a statement provided by the presidential campaign.

Holder, who stepped down as attorney general in 2015, will campaign with Clinton in South Carolina this weekend, including Sunday's Democratic debate sponsored by the Congressional Black Caucus.

Secretary of State Hillary Clinton and Attorney General Eric Holder participate an event on May 16, 2011, in Washington.

"Our next president can't shy away from building on the progress of President Obama, which is why Hillary Clinton is the candidate that we need in the White House," Holder said in a statement. "She has the experience and right judgment to deliver results for families across the country."

In addition to campaigning with Clinton, Holder will also deliver the keynote address on her behalf at a church service on Sunday at Morris Street Baptist Church in Charleston, South Carolina.
