The 80-year-old has since been released and returned with students Tuesday.
As The Washington Post reports, Jackson was entering Blackburn University Center— the site of the protests since they started on October 12— when he fell and hit his head Monday. He was then “taken to Howard University Hospital where he underwent a series of tests, including a CT scan, which came back normal” and kept overnight for observation.
Prior to this week’s visits, Jackson had also spent time over the weekend offering student protestors support. “Better together. Keep hope alive,” he started in a call-response chant.
The activist has also been fighting for Jelani Day in his home state of Illinois, leading protests last week to investigate the circumstances around the graduate student’s killing.
