Washington (CNN) Florida Democratic gubernatorial candidate Andrew Gillum on Sunday said a robocall aimed at mocking his race was "deeply regrettable" and took aim at his Republican opponent for saying Florida voters should not "monkey this up" by electing Gillum.

The 78-second prerecorded message , obtained by CNN, is narrated by a man speaking in a caricature of a black dialect with cartoonish jungle noises in the background. It ends with a disclaimer that it was paid for by The Road to Power, a white supremacist and anti-Semitic video podcast hosted by Scott Rhodes of Idaho.

The phone message went to Florida residents, but it's unclear how many received it. The Tallahassee Democrat first reported the robocall.

Asked about the robocall, Gillum, the mayor of Tallahassee, told CNN's "State of the Union, "I have to tell you I find this deeply regrettable."

Stephen Lawson, a spokesman for Gillum's Republican opponent, Rep. Ron DeSantis, condemned the call, calling it "absolutely appalling and disgusting" and saying the campaign "will continue to focus solely on the issues that Floridians care about and uniting our state."
