In the letter of endorsement, Humphries wrote the following:
Dear Alumni and Friends:
Commissioner Andrew Gillum is running for Mayor of the City of Tallahassee, Florida. Andrew is an outstanding alumnus of Florida A&M University (FAMU). It was during his tenure, as the student government association (SGA) president, that he served as our inaugural student representative on the FAMU Board of Trustees. Having worked directly with Andrew, I can attest to his leadership as a consensus builder, negotiator, collaborator and listener. He is an example of the leadership, dedication and drive we instill in our alumni. As the City of Tallahassee moves forward, it is important to have leaders like Andrew.
