The parade's grand marshal was Lea DeLaria, star of the "Orange is the New Black" Netflix show and an Illinois native.
"I've been to Gay Pride all over the worked from Tel Aviv to San Paolo to Chicago and the Chicago Pride is so much fun," DeLaria said.

"It's more important than ever, this march to reassert our common values but we continue to battle to make sure that the voices that are on the periphery are brought in to the American family, the Chicago family," Emanuel said.
