ATLANTA (AP) — After spending months arguing that Republican Senate candidate Herschel Walker is “not ready” for high elected office, Sen. Raphael Warnock of Georgia is intensifying his critique ahead of Election Day to say the celebrity athlete is fundamentally unfit for Capitol Hill. From a rally with former President Barack Obama to a statewide bus tour that runs through the eve of Election Day on Tuesday, Warnock has hammered Walker as a “pathological liar” who has exaggerated his business, academic, professional and philanthropic achievements and been accused of violence against his family members and of paying for girlfriends’ abortions despite his public opposition to the procedure. “This is a man who lies about the most basic facts of his life,” Warnock said on a stage he shared with Obama.
