Costco shoppers warned that Al Sharpton's involvement in a 'buy in' celebrating their DEI policies could be a 'kiss of death' for the retail giant.

The show of support from Sharpton's organization came after Costco and its shareholders defied President Donald Trump and conservative activists by voting to stick to their diversity, equity and inclusion policies last week.

The controversial civil right activist led 100 members of his National Action Network through the Harlem Costco to spend their money in a show of gratitude for the decision.
