  • Antiviolence and police brutality activist calls for a Bud Billiken Parade boycott

Activist Ja’Mal Green is calling for a boycott of the annual Bud Billiken Parade, scheduled to take place Saturday. Green says parade organizers won’t allow him and other activists to march if they plan to use the platform to speak out about police brutality. “Which is ridiculous because it’s a black parade, and black people are getting killed every day by police,” Green told DNAinfo Chicago. “The Bud Billiken Parade would have been used as a platform to continue to wake people up, continue to put the protest and activism in their face.” The yearly parade, founded in 1929, starts in Bronzeville and ends in Washington Park.

  • Hillary Clinton and Donald Trump have been booed at Wrigley Field

GOP presidential nominee Donald Trump and Democratic presidential nominee Hillary Clinton have at least one thing in common: they’ve both been booed by Cubs fans at Wrigley Field.
