Celebrities React to Caitlyn Jenner's Emotional ESPY Awards Speech

Russell Simmons, Monica Lewinsky and Rosie Perez expressed support.

Jenner –- a 1976 Olympic gold medalist in the decathlon -– accepted the Arthur Ashe Courage Award after revealing earlier this year that she is a woman, and using her platform to shed light on transgender issues. In Wednesday’s speech, Jenner said she struggled with her “situation” privately for decades, before deciding to come forward.

"This transition has been harder on me than anything I could imagine," she said, adding that "trans people ... deserve your respect."

Laverne Cox believes the speech marks a milestone for the transgender community.

Former professional football player Wade Davis is motivated by Jenner’s message.
