Democratic Senator Raphael Warnock debated Libertarian Senate candidate Chase Oliver in Atlanta, Georgia, on Sunday. Next to the two men stood an empty lectern for Republican candidate Herschel Walker, Senator Warnock’s main competitor, who refused to participate in the debate. The event came two days after Warnock and Walker faced off Friday night in what is expected to be their only debate. Walker was forced to defend his anti-abortion stance, after a former romantic partner recently said the ex-football player once paid for her to have an abortion and later urged her to terminate another pregnancy. She had the child. Walker has denied the claims. Senator Warnock, meanwhile, defended abortion rights in light of the recent reversal of Roe v. Wade.

Sen. Raphael Warnock: “A patient’s room is too narrow and small and cramped a space for a woman, her doctor and the United States government. We are witnessing right now what happens when politicians — most of them men — pile into patients’ rooms.”

Warnock and Walker also clashed over their positions on the police, Medicaid expansion and who they supported as the respective leaders of their parties.
