Reed sent a letter this week to United Consulting, the Norcross-based engineering firm where Hunter — who has faced ongoing backlash after calling civil rights leader and U.S. Rep. John Lewis a "racist pig" on Facebook — works as a vice president of business development. The firm also does a significant amount of business with the city of Atlanta.

“As Mayor, I am writing personally to let you know that the City of Atlanta finds Mr. Hunter’s toxic remark to be insulting, reprehensible and unacceptable to this administration,” Reed wrote in his letter, addressed to United Consulting CEO Reza Abree. “Please let me know by close of business Monday, February 27 how you plan to resolve this matter.”
