Chaka Khan (Aaron Leitko/The Washington Post)

Venue: Longworth House Office Building.

Concern: The recent uptick in autism diagnoses among African American and Latino boys.

Bona Fides: 10-time Grammy winner, aunt of an autistic boy.

Backup: Her sister/manager Tammy McCrary, actress Tisha Campbell-Martin, D.L. Hughley’s wife LaDonna — all moms of autistic boys, who’ve made a documentary, “Colored My Mind,” about their struggle.

What she wants: For Congress to reauthorize the Combating Autism Act, set to expire this year.

How she looked: Simple black pantsuit, heavy gold bling. When asked for a photo, she struck a pose with a black-and-red fan.

Quote: “It’s a struggle for mankind. This transcends everything, all the little petty groups.”
