You probably remember the name. If you lived in Michigan during the early 2000s, Attorney General Mike Cox was everywhere. He was the young, aggressive Republican who broke a nearly 50-year Democratic streak to take the office. He was a former Marine, a Wayne County homicide prosecutor, and a guy who didn't seem to mind a street fight.
Honestly, his career has been a wild ride. From taking on the "unsolvable" cold cases of serial killers to a public admission of an extramarital affair that nearly derailed everything, Mike Cox is anything but boring. Now, as he steps back into the spotlight for the 2026 gubernatorial race, people are asking the same questions they did twenty years ago. Is he a reformer or a firebrand? Can he actually win?
The Rise of a Homicide Prosecutor
Mike Cox didn't start in a plush law office. He started in the Marine Corps. That "infantryman mentality" followed him into the Wayne County Prosecutor’s Office. Before he ever thought about being the state’s top cop, he was in the trenches of Detroit's justice system. He handled over 125 jury trials. He eventually became the Chief of the Homicide Unit.
When he ran for Attorney General in 2002, he was a massive underdog. Republicans hadn't won that seat since 1955. But Cox leaned into his "tough on crime" roots. He barely squeaked out a win, but it was enough to shift the political landscape in Lansing for nearly a decade.

Taking on the Cases No One Wanted
Once in office, Cox did something pretty unusual for a high-level politician. He went back to his roots. He created a specialized Cold Case Unit. This wasn't just for show. His team actually secured convictions in cases that had been gathering dust for thirty years.
One of the biggest wins was putting away Coral Watts, a notorious serial killer. Most people had given up on seeing justice for those victims. Cox’s office also tracked down the killers of Janet Chandler, a 1979 murder that had haunted the Holland area for decades. He basically turned the Attorney General's office into a high-stakes detective agency.
The Scandal and the "Fieger War"
It wasn't all courtroom victories, though. In 2005, Mike Cox held a press conference that no politician ever wants to hold. He admitted to an extramarital affair.
Kinda shocking? Yeah. Especially for a guy who ran on a family-man platform.
But the story got even weirder. Cox claimed he was being blackmailed. He alleged that associates of the famous (and controversial) trial lawyer Geoffrey Fieger were threatening to leak the affair unless Cox dropped an investigation into Fieger's campaign finances. Fieger denied it, of course. He called for Cox to resign. The two spent years trading legal blows in what felt like a personal vendetta played out in the headlines.
Surprisingly, the voters didn't care as much as the pundits expected. Cox won re-election in 2006 by a comfortable margin. He had a knack for moving past the noise and focusing on "bread and butter" issues like child support and utility rates.
What Mike Cox Actually Did for Michigan
If you look past the scandals, the sheer volume of work his office moved is staggering. He had nearly 270 attorneys working for him, and he wasn't shy about using them.
- Child Support: He founded the first-of-its-kind Child Support Unit. It ended up collecting nearly $500 million for families who had been left high and dry.
- The Asian Carp Fight: He took the State of Illinois and the U.S. Army Corps of Engineers all the way to the Supreme Court. Why? To stop invasive Asian Carp from entering Lake Michigan and destroying the state’s fishing industry.
- Health Care Costs: He was a constant thorn in the side of Blue Cross Blue Shield of Michigan, fighting rate hikes and challenging their move to purchase for-profit companies.
- The ACA Lawsuit: In 2010, he joined 12 other states to challenge the constitutionality of the Affordable Care Act (Obamacare), arguing it overstepped federal authority.
He was a "constitutional conservative" before it was a trendy buzzword. He supported the Michigan Civil Rights Initiative, which banned race and gender preferences in public hiring and education. It was a move that earned him plenty of enemies, but it solidified his base.
The Private Practice Years and the Robert Anderson Case
After term limits pushed him out in 2010, Cox didn't just disappear into a corporate boardroom. Well, he did join a big firm for a bit, but then he started the Mike Cox Law Firm.
Lately, he’s been back in the news for representing hundreds of survivors of sexual abuse. Specifically, he was a lead counsel for the former University of Michigan students who were abused by sports doctor Robert Anderson. This wasn't just a legal case for him; it was personal. He’s a U of M grad. Seeing his alma mater cover up decades of abuse clearly struck a chord.
He also successfully represented the "Unlock Michigan" committee during the COVID-19 pandemic. They were the ones fighting to repeal the emergency powers used by Governor Gretchen Whitmer. It proved that even out of office, Cox still knew how to navigate the levers of power.

Why Attorney General Mike Cox Matters in 2026
You might think a guy whose peak political years were twenty years ago would be irrelevant. You’d be wrong. In 2025, Cox announced he was running for Governor again.
He’s currently sitting on a massive campaign chest—millions of dollars—and he’s leading many of the early conversations in the Republican primary. He’s positioning himself as the "adult in the room" who has actual experience running a massive government agency.
But can he win over a new generation of voters?
Younger Michiganders don't remember the Coral Watts conviction. They don't remember the fight over Asian carp. They see a veteran politician in a world that is increasingly skeptical of "the establishment."
Actionable Insights for Michigan Residents
If you're following the return of Mike Cox, here is what you should keep an eye on:
- Check the Case Files: If you're curious about his legal record, look at the settlements his firm has won for survivors of institutional abuse. It gives you a clear picture of his current legal priorities.
- Follow the Money: Watch the 2026 campaign finance reports. Cox is a fundraising powerhouse, and where that money comes from will tell you who expects him to win.
- Evaluate the "Experience" Argument: Compare his tenure as Attorney General with the current administration. Regardless of your politics, his "do more with less" approach—reducing staff by 20% while increasing case volume—is a metric worth studying.
- Watch the Debates: Cox is a trial lawyer at heart. He thrives in a confrontation. In a crowded primary field, his ability to out-argue opponents will be his biggest asset.
Mike Cox is a complicated figure. He’s a Marine, a prosecutor, a family man with a public mistake, and a legal strategist. Whether you love him or hate him, you can't ignore him. He’s spent thirty-five years in the middle of Michigan's biggest fights, and it looks like he’s ready for one more.
