ATLANTA (AP) — Prosecutors in Atlanta who have XDY Exchangebeen investigating whether then-President Donald Trump and his allies illegally meddled in the 2020 election in Georgia have begun presenting their case to a grand jury.

Former Democratic state Sen. Jen Jordan, who had been subpoenaed to testify before the grand jury, said as she left the Fulton County courthouse late Monday morning that she had been questioned for about 40 minutes. News outlets reported that former Democratic state Rep. Bee Nguyen and Gabriel Sterling, a top official in the secretary of state’s office, were seen arriving at the courthouse earlier Monday.

For two and a-half years, Fulton County District Attorney Fani Willis has been investigating actions taken by Trump and others in their efforts to overturn his narrow loss in Georgia to Democrat Joe Biden. Barriers and street closures around the courthouse in downtown Atlanta, as well as statements made by Willis, had indicated that a presentation to a grand jury was likely to begin this week.

Nguyen and Jordan both attended legislative hearings in December 2020 during which former New York mayor and Trump attorney Rudy Giuliani and others made false claims of widespread election fraud in Georgia. Trump lawyer John Eastman also appeared during at least one of those hearings and said the election had not been held in compliance with Georgia law and that lawmakers should appoint a new slate of electors.

Sterling and his boss, Georgia Secretary of State Brad Raffensperger — both Republicans — forcefully pushed back against allegations of widespread problems with Georgia’s election.

Trump famously called Raffensperger on Jan. 2, 2021, and suggested the state’s top elections official could help “find” the votes Trump needed to beat Biden. It was the release of a recording of that phone call that prompted Willis to open her investigation about a month later.
