Investigators are working to remove racist, anti-Kamala Harris signs from bus stops in the Denver area on Thursday.

“I wish I could say I was surprised, but in a year when a Black woman could become president, those with hate in their hearts will coordinate these kinds of cruel, expensive campaigns to stoke division,” Denver City Councilwoman Shontel Lewis said in a statement on X.

Photos posted by Lewis show signs bolted to a Regional Transportation District bus stop pole at the corner of Colfax Avenue and Garfield Street, outside National Jewish Health and just west of Colorado Boulevard.

The bus stop is located on the northern edge of the Congress Park neighborhood in Denver.

A white sign reads: “Blacks must sit in the back of the bus. Kamala’s migrants sit in the front.” Another yellow warning sign on the same pole warns passengers about “Kamala’s illegals” and shows images of people running, meant to mimic immigrants crossing the border.

The warning sign is modeled after a real road sign that used to be in place in California warning drivers near the San Diego border to watch for migrants running across the highway. The last sign was removed in 2018.

Lewis said officials from RTD, the Denver Department of Transportation and the Denver Police Department are working to remove all reported signs.
