Former Presidents Barack Obama and Bill Clinton, and former Secretary of State Hillary Clinton will attend Rep. Elijah Cummings' funeral in Baltimore on Friday as the nation bids farewell to the Maryland Democrat who served on Capitol Hill 23 years.

Spokeswoman Katie Hill confirmed that Obama would attend in a tweet Wednesday night. She said Cummings’ widow, Maya Rockeymoore Cummings, asked Obama to "deliver remarks about the remarkable life and legacy of one of this country’s finest public servants."

Cummings, 68, died last week of complications related to longstanding health issues. He had previously been treated for heart and knee issues, according to The Associated Press and had cancer, The Baltimore Sun reported.

"Michelle and I are heartbroken over the passing of our friend, Elijah Cummings," Obama said in a statement after the congressman's death. "As Chairman of the House Oversight Committee, he showed us all not only the importance of checks and balances within our democracy, but also the necessity of good people stewarding it."

Cummings was a personal friend of Obama's and was an early supporter of his 2008 presidential run.

The funeral will be held at the New Psalmist Baptist Church, where Cummings worshiped for nearly 40 years.

In addition to Obama and Hillary Clinton, House Speaker Nancy Pelosi, D-Calif., and former Rep. Kweisi Mfume will join Rockeymoore Cummings, Cummings' brother and his daughters as speakers at the funeral, according to Reuters and The Washington Post.

Cummings won Mfume's House seat in a special election in 1996 after Mfume left Congress to become president of the National Association for the Advancement of Colored People.

Last week, Bill Clinton said Cummings "was a resounding voice of moral courage who fought the good fights for the people of Baltimore."

Hillary Clinton said Cummings was "a man of principle who championed truth, justice and kindness. He fiercely loved his country and the people he served."

The former House Oversight and Reform Committee Chairman will lie in state in the U.S. Capitol on Thursday. On Wednesday, mourners paid respects to Cummings as his body lay in repose at Morgan State University, a historically black college in Cummings' district. Cummings served on the school's Board of Regents for 19 years.
