A video highlighting the historic campaigns of Shirley Chisholm and the Rev. Jesse Jackson played during the first night of the DNC. After the video, Jackson appeared on stage to a loud standing ovation.When she ran in 1972, Chisholm was the first Black woman to mount a nationwide campaign for the Democratic Party's nomination. Chisholm, who died in January 2005 at age 80, was also the first Black woman to be elected to the U.S. Congress. She served seven terms as a congresswoman. Jackson, who is a well-known civil rights leader, ran for the Democratic nomination in 1984 and then again in 1988.Neither Jackson nor Chisholm succeeded in securing the party nod, but speakers in the video discuss how both of their campaigns for president in the 1970s and 1980s helped to "reshape" the Democratic National Committee, and "pave the way" for former President Barrack Obama to successfully run for president in 2008. Vice President Kamala Harris is the first Black woman to ever successfully receive the DNC nomination. Jackson, 82, entered the stage in a wheelchair, holding up both thumbs up in triumph to a cheering crowd. The Rev. Al Sharpton and others surrounded Jackson. Jackson, an ordained Baptist pastor, did not speak to the convention.Multiple speakers gave shoutouts to Jackson, who was also the subject of a video broadcast at the event’s hall. The video noted that Harris was “standing on the shoulder of giants” such as Jackson. The Associated Press contributed to this report.
