Earlier Wednesday, DeSantis told Florida voters not to “monkey this up” by voting for Gillum. Gillum, a progressive candidate backed by Sen.

Critics and Democratic figures were quick to call DeSantis’ comment racist, with Gillum’s campaign manager saying it was more like a "bull horn" than a "dog whistle."

DeSantis’ campaign defended the comments, saying it was “absurd” to say the expression was racist.

Gillum tied his opponent’s comments to President Trump’s rhetoric, saying DeSantis was “taking a page directly from the campaign manual of Donald Trump.”

Trump has also been accused of racism in past comments. He has repeatedly attacked the intelligence of black athletes and lawmakers and has been criticized for his comments on immigration, especially from Mexico, and crime in low-income communities.
