Former President Donald Trump said Tuesday he could soon be facing his third criminal indictment of the year. No president or former president has ever been charged with one crime, let alone three, so terms like "historic" and "unprecedented" no longer feel large enough to explain what is going on here.

What we know for sure is that Trump said he's been informed he's a target of the Justice Department's investigation into the January 6, 2021, insurrection and efforts to overturn the 2020 presidential election and that the former president has been invited to appear before the federal grand jury in Washington, DC, that's been hearing evidence related to that investigation.

We should wait to see what, if anything, Smith ultimately alleges against Trump or his associates. But what Trump wanted to do to erase his election loss and how he planned to do it has been well documented in the years since.

Here's an attempt to synthesize what CNN has been reporting in recent months along with what the House select committee that investigated January 6 laid out in its hearings and what Trump said publicly in 2020 and 2021. There are strong indications that whatever case Smith could bring would revolve around Trump's public and behind-the-scenes effort to circumvent the Electoral College.

Americans technically vote for electors when they vote for presidential candidates in early November. Electors are real people - often party activists - and the electors for the popular-vote winner in each state meet in their statehouses and cast electoral votes in mid-December (December 14 in 2020). Those Electoral College votes are then counted in Congress as the vice president presides on January 6. The new president is sworn in on January 20.
