Progressive Activist Cori Bush Ousts Longtime Missouri Rep. Lacy Clay

Cori Bush, a nurse and Black Lives Matter activist, has ousted longtime Missouri U.S. Rep. William Lacy Clay in a Democratic primary, according to The Associated Press.

It's the latest example of a progressive challenger topping a long-tenured Democratic incumbent.

"It is historic that this year, of all years, we're sending a Black, working-class single mother, who has been fighting for Black lives since Ferguson, all the way to the halls of Congress," she said in her victory speech.
