evidence: An Atlanta-area prosecutor plans to scrutinize a post-Election Day phone call between Sen. Lindsey O. Graham (R-S.C.) and Georgia Secretary of State Brad Raffensperger as part of a criminal investigation into whether former president Donald Trump or his allies broke Georgia laws while trying to reverse his defeat in the state, according to a person familiar with the probe. [...] During their conversation, Graham asked the Georgia secretary of state whether he had the power to toss out all mail ballots in certain counties, Raffensperger told The Washington Post in an interview days later. He said Graham appeared to be asking him to improperly find a way to set aside legally cast ballots. [...] Willis announced Wednesday that her office would investigate potentially criminal attempts to influence the state election result, including calls Trump made to Raffensperger and to the state’s chief elections investigator.
