Ellen DeGeneres’ brother came to his sister’s defense this week as allegations about the daytime talk show host’s workplace demeanor continue to make headlines. 

Actor and former “The Daily Show” correspondent Vance DeGeneres described his sibling as “one of the kindest, most generous people you’ll ever meet” on Twitter Tuesday. To those who believe Ellen would “knowingly allow bullying or racism” to take place on her show, he added, “You don’t know my sister.”
