Washington (CNN) A white supremacist group that targeted Florida gubernatorial candidate Andrew Gillum with racist robocalls is now targeting Georgia Democratic gubernatorial candidate Stacey Abrams.

The prerecorded phone message features a voice impersonating Oprah Winfrey, who was in Georgia on Thursday stumping for Abrams, and contains racist and anti-Semitic rhetoric.

The robocall went out to Georgia voters, but it is unclear how many received it.

Abrams' Republican opponent, Brian Kemp, strongly denounced the automated call, calling it "absolutely disgusting" in a statement Friday.
