Crowds of mourners line up for memorial services for Jesse Jackson at his Chicago organization

CHICAGO — A line of mourners streamed through a Chicago auditorium Thursday to pay final respects to the Rev. Jesse Jackson Sr. as cross-country memorial services began in the city the late civil rights leader called home.

The protege of the Rev. Martin Luther King Jr. and two-time presidential candidate will lie in repose for two days at the headquarters of the Rainbow PUSH Coalition before events in Washington and South Carolina, where he was born.

Family members wiped away tears as the casket was brought into the stately brick building. Flowers lined the sidewalks where people waiting to enter watched a large video screen playing excerpts of Jackson’s notable speeches. Inside, Jackson’s children, Chicago Mayor Brandon Johnson and the Rev. Al Sharpton were among those who stood by the open casket to shake hands and hug those coming to view the body of Jackson, dressed in a suit and blue shirt and tie.

“The challenge for us is that we’ve got to make sure that all he lived for was not in vain,” Sharpton told reporters. “Dr. King’s dream and Jesse Jackson’s mission now falls on our shoulders. We’ve got to stand up and keep it going.”

Jackson died last week at age 84 after battling a rare neurological disorder that affected his mobility and ability to speak in his later years.

Remembrances have already poured in from around the globe, and several U.S. states, including Minnesota, Iowa and North Carolina, are flying flags at half-staff in his honor.

But perhaps nowhere has his death been felt as strongly as in the nation’s third-largest city, where Jackson lived for decades and raised his six children, including a son who is a congressman.

Bouquets have been left outside the family’s Tudor-style home on the city’s South Side for days. Public schools have offered condolences, and city trains have used digital screens to display Jackson’s portrait and his well-known mantra, “I am Somebody!”

His causes, both in the United States and abroad, were countless: Advocating for the poor and underrepresented on issues including voting rights, job opportunities, education and health care. He scored diplomatic victories with world leaders, and through his Rainbow PUSH Coalition, he channeled cries for Black pride and self-determination into corporate boardrooms, pressuring executives to make America a more open and equitable society.

“We honor him, and his hard-earned legacy as a freedom fighter, philosopher, and faithful shepherd of his family and community here in Chicago,” the mayor said in a statement.

Next week, Jackson will lie in honor at the South Carolina Statehouse, followed by public services. According to Rainbow PUSH’s agenda, Gov. Henry McMaster is expected to deliver remarks; however, the governor’s office said Thursday that his participation wasn’t yet confirmed. Jackson spent his childhood and started his activism in South Carolina.

Details on services in Washington have not yet been made public. However, he will not lie in honor at the United States Capitol rotunda after a request for the commemoration was denied by the House Speaker Mike Johnson’s office.

The two weeks of events will wrap up next week with a large celebration of life gathering at a Chicago megachurch and finally, homegoing services at the headquarters of the Rainbow PUSH Coalition.

Family members said the services will be open to all. Mourners of all ages — from toddlers in strollers to elderly people in wheelchairs — came to pay respects.

“Our family is overwhelmed and overjoyed by the amazing amount of support being offered by common, ordinary people who our father’s life has come into contact with,” his eldest son, Jesse Jackson Jr., said before the services began. “This is a unique opportunity to lay down some of the political rhetoric and to lay down some of the division that deeply divides our country and to reflect upon a man who brought people together.”
