ATLANTA — Days after news broke in January 2021 that President Donald Trump had tried to pressure the Georgia secretary of state to overturn the 2020 election results, Fulton County District Attorney Fani Willis launched a criminal investigation.

Since then, the investigation appears to have dramatically broadened, and investigators have identified more than 100 people of interest as they probe what Trump or his allies did in the weeks after the election. In January, Willis asked a judge to convene a special grand jury that has broad investigative powers. In May, 26 people were chosen to serve.

In September, Willis told The Washington Post she believes targets of the investigation, if indicted and convicted, may face “prison sentences” given information already obtained by the grand jury.

Here’s what you need to know:

The Jan. 6 insurrection

Congressional hearings: The House committee investigating the attack on the U.S. Capitol held a series of high-profile hearings to share its findings with the U.S. public. In what was likely its final hearing, the committee issued a surprise subpoena seeking testimony from former president Donald Trump. Here’s a guide to the biggest hearing moments so far.

Will there be charges? The committee could make criminal referrals of former president Donald Trump over his role in the attack, Rep. Liz Cheney (R-Wyo.) said in an interview.

What we know about what Trump did on Jan. 6: New details emerged when Hutchinson testified before the committee and shared what she saw and heard on Jan. 6.

The riot: On Jan. 6, 2021, a pro-Trump mob stormed the U.S. Capitol in an attempt to stop the certification of the 2020 election results. Five people died on that day or in the immediate aftermath, and 140 police officers were assaulted.

Inside the siege: During the rampage, rioters came perilously close to penetrating the inner sanctums of the building while lawmakers were still there, including former vice president Mike Pence. The Washington Post examined text messages, photos and videos to create a video timeline of what happened on Jan. 6.
