Il Nuovo Postiglione - 'Harder path': Obama attacks Trump at Jesse Jackson memorial

Obama joined former presidents Joe Biden and Bill Clinton to mark the life of Jackson after his death at age 84.

"Each day we wake up to some new assault on our democratic institutions, another setback to the idea of the rule of law, an offense to common decency," Obama said after receiving a rapturous welcome at the event in Chicago.

"Every day, you wake up to things you just didn't think were possible.

"It may be tempting to get discouraged, to give into cynicism... (but) this man, Reverend Jesse Lewis Jackson, inspires us to take a harder path."

Ahead of the speeches, a choir sang as attendees photographed a large panel emblazoned with one of Jackson's mantras "keep hope alive."

A blue-lit image of Jackson was projected on a giant screen behind an altar.

Jackson, who died on February 17, was a close associate of Martin Luther King Jr in the 1960s and remained a prominent voice of African Americans on the national stage for more than six decades.

In 1960, he participated in his first sit-in, in Greenville, South Carolina, and then joined Alabama's Selma-to-Montgomery civil rights marches in 1965, where he caught King's attention.

Jackson, a Baptist minister, later emerged as a mediator and envoy on several notable international fronts.

He became a prominent advocate for ending apartheid in South Africa, and in the 1990s served as presidential special envoy to Africa for Bill Clinton.

Missions to free US prisoners took him to Syria, Iraq and Serbia.

He founded the Rainbow PUSH Coalition, a Chicago-based nonprofit organization focused on social justice and political activism, in 1996.

He is survived by his wife and six children.
