The Rev. Jesse Jackson has died at age 84.

Jackson, known as one of the pioneers of the civil rights movement, continued that work until his death.

The Rev. Jesse Jackson made several trips to Connecticut in his lifetime.

He lectured at Yale many times and was arrested there in 2003 while protesting in support of union workers.

He also marched with 2,000 others through Bridgeport in 1991 for Rebuild America, supporting union workers and community groups.

In April, Jackson was diagnosed with a rare brain condition related to Parkinson’s.

He rose to prominence in the civil rights era and stood alongside the Rev. Martin Luther King Jr. in several demonstrations.

His activism spanned decades, including two runs for the Democratic presidential nomination, in 1984 and 1988. Jackson was at the motel in Memphis, Tennessee, with King when he was assassinated in 1968, fueling his relentless pursuit of civil rights and equality.

Jackson’s family said he died peacefully Tuesday morning.

Jackson condemned Donald Trump’s presidency, saying, “Fifty years of civil rights have been threatened.”
