State prosecutors in Michigan announced criminal charges Tuesday against the 16 Republicans who served as fake electors in 2020, a watershed moment in the still-ongoing federal and state investigations into the 2020 election aftermath.

Some of the GOP electors in Michigan were local activists who were recruited to serve as "fake electors," all while inaccurately believing there was still a chance that then-President Donald Trump might secure a second consecutive term. Others were well-connected GOP operatives. The group of 16 fake electors includes current and former state GOP officials, a Republican National Committee member, a sitting mayor, a school board member and Trump supporters who were the plaintiffs in a frivolous lawsuit that tried to overturn the 2020 results.

After the 2020 election wrapped up, some of these individuals publicly said they didn't realize they were potentially breaking the law by signing the fake certificates. Others are still peddling the lie that the election was stolen. CNN has reached out to the 16 fake electors for comment about the criminal charges.

Here's what we know about the 16 fake electors facing state charges.

Meshawn Maddock, 55, was co-chair of the Michigan Republican Party during the 2020 campaign and is married to a GOP member of the Michigan House of Representatives. CNN previously reported that she publicly bragged about the Trump campaign's involvement in the fake elector scheme. The Maddocks spoke at a pro-Trump event in Washington, DC, one day before the insurrection on January 6, 2021, and Meshawn Maddock was in DC on the day of the attack, though she wasn't at the US Capitol.

Kathy Berden, 70, is one of the Republican National Committee members representing Michigan. She was previously one of the pro-Trump delegates at the Republican National Convention in summer 2016.

Marian Sheridan, 69, is the grassroots vice chairwoman of the Michigan Republican Party. She was also one of the plaintiffs in a frivolous lawsuit that tried to overturn the results of the 2020 election in Michigan.

Kent Vanderwood, 69, is the current mayor of Wyoming, Michigan, a small city near Grand Rapids. He was previously a longtime member of the Wyoming City Council and won the mayor's race last year. During the 2020 campaign, he was chair of the 2nd District Republican Party, according to local press reports.

Stanley Grot, 71, is the Shelby Township clerk, in a small western Michigan town. He was appointed in 2012.

Amy Facchinello, 55, was elected in 2020 as a member of the school board in Grand Blanc, which is a suburb of Flint, Michigan. She was previously vice chairwoman of the Genesee County Republican Party. CNN previously reported that she has repeatedly promoted QAnon-related material on her social media accounts.

Mary-Ann Henry, 65, is the treasurer of the 7th Congressional District Republican Committee, according to its website. The district includes Michigan's capital city of Lansing and several surrounding counties.

Michele Lundgren, 73, was the Republican nominee in 2022 for a Detroit-based seat in the Michigan House of Representatives, but lost the heavily Democratic district in a landslide. Regarding the fake electors plot, she told CNN last year, "We were called on the phone, asked if we'd come and support President Trump and sign something, and we all went to Lansing. ... We were just told to show up and sign this paper. If we had any information about it being untoward or illegal, we would not have done it."

Clifford Frost, 75, is a realtor who unsuccessfully ran for the Macomb County Board of Commissioners last year. He was a GOP poll-watcher in Detroit during the 2020 primary, according to the Detroit Free Press. In recent days, he has shared pro-Trump conspiracy theories about alleged voter fraud on social media.

John Haggard, 82, was one of the plaintiffs in a frivolous lawsuit that tried to overturn the 2020 results in Michigan. The lawsuit was dismissed and the lawyers who brought it were sanctioned by a judge. He served as a legitimate Trump elector from Michigan in 2016, when Trump narrowly won the state.

Timothy King, 56, was also one of the plaintiffs in a frivolous lawsuit that tried to overturn the 2020 results in Michigan. The lawsuit was dismissed and the lawyers who brought it were sanctioned by a judge.

Rose Rook, 81, is a member of the executive committee of the Van Buren County Republicans, according to its website.

Mayra Rodriguez, 64, is a lawyer who is facing potential disciplinary proceedings with the Attorney Discipline Board, stemming from her participation in the fake electors plot, according to the Detroit Free Press.

Ken Thompson, 68 was brought in to replace one of the original GOP electors that was recruited to serve before the 2020 election. A Michigan GOP official testified to the House select committee that investigated January 6, 2021, that Thompson replaced an original elector who was "uncomfortable with the whole thing" and refused to participate.

James Renner, 76, was also brought in later in the process to replace one of the original GOP electors. He is from Lansing.
