Senator Mitch McConnell has been out of the U.S. Senate since mid-June 2026. His office says he fell, hit his head hard enough to briefly pass out, and later developed pneumonia. He’s been in a rehab facility ever since, working on physical therapy. His staff insists he is “fit to serve.” But no one has said when he might actually come back to work.
This kind of story isn’t new, and it isn’t really about McConnell alone. It’s about a much bigger question that most Americans have never had to think about: What happens when a member of Congress becomes too sick, too injured, or too impaired to do the job — but doesn’t resign?
The surprising answer is: almost nothing happens automatically. There is no rule that forces a senator or House member out of office just because they can’t function. The Constitution simply didn’t plan for this problem, and that gap has caused real trouble more than once.
Three Real Cases, Three Different Outcomes
To understand how this gap plays out, it helps to look at three real examples. Each one shows a different way the same basic problem can unfold.
Case 1: Hidden from the public — Kay Granger
In 2024, Representative Kay Granger of Texas simply stopped showing up. She missed votes in the House for about five months, and her offices in Washington and Texas weren’t answering calls. Eventually, a local news outlet tracked her down and found she was living at a senior living facility in Fort Worth. Only after this was reported did her family confirm she had been dealing with dementia. Her son pushed back on claims she was in a memory care unit specifically, saying she lived in the independent living section instead. Either way, the public had no idea what was happening to their representative until outsiders investigated and found her.
Case 2: Announced, but unclear — Mitch McConnell
McConnell’s situation is different. His office has confirmed he was hospitalized, named his injuries in general terms, and released occasional updates and photos. So in one sense, this case is more transparent than Granger’s. But the updates don’t say how much McConnell can actually do. Is he reading briefings? Voting from the rehab facility? Fully aware of Senate business? The public doesn’t know, and his office controls exactly how much gets shared and when.
Case 3: Fully public, still unsolvable — Karl Mundt
Go back further, to 1969, and you find a case where there was no ambiguity at all. Senator Karl Mundt of South Dakota suffered a severe stroke that left him unable to speak or move normally. Everyone knew it. It wasn’t hidden. His wife, Mary, ran his Senate office in his place, and Senate Republicans publicly and repeatedly asked him to resign so someone else could take over the seat. Mary Mundt refused on his behalf. Eventually, in 1972, Senate Republicans took away his committee assignments and seniority as a kind of punishment. But that was symbolic. Mundt still legally held his Senate seat until his term ended in January 1973. He never ran again, but he was never forced out either.
Put these three cases side by side and a pattern shows up. It doesn’t matter whether the public finds out by accident, gets partial updates, or knows the full truth right away. None of that changes the outcome. There is no built-in mechanism that removes someone from Congress just because they can’t do the job anymore.
Why There’s No Automatic Fix
The Constitution actually spells out very clearly how a Senate seat becomes empty. The 17th Amendment says a vacancy happens through death, resignation, or expulsion. That’s it. There’s no category for “too sick to serve” or “hasn’t cast a vote in six months.”
Expulsion is technically possible. Article I of the Constitution lets each chamber of Congress kick out one of its own members, but only with a two-thirds vote. In practice, this has almost always been used for serious misconduct, like disloyalty or corruption — not for someone who is simply too ill to work. No one wants to be the lawmaker who votes to expel a colleague for being sick, especially a colleague they’ve served alongside for years.
There’s also no substitute for actually showing up. Unlike some committees in the House, the Senate does not allow proxy voting, meaning someone can’t vote on a senator’s behalf while that senator is absent. So an incapacitated senator’s seat isn’t just “asleep” — it’s genuinely missing from important votes, which matters a lot in a closely divided Senate.
Why Nobody Fixes This
If the problem is this obvious, why hasn’t it been solved? A few reasons keep coming up.
First, politics. In a Senate where the majority might only be one or two seats, keeping a struggling senator technically in office — even if they can’t function well — can matter more to a party than replacing them with someone healthier. If that senator resigned, a governor from the other party might get to appoint their replacement, possibly flipping control.
Second, loyalty and family dynamics. In both the Mundt and Granger cases, family members controlled information and, in Mundt’s case, controlled the decision to resign. That’s an enormous amount of power resting with people who were never elected to anything.
Third, plain discomfort. Publicly pressuring a sick, elderly colleague to leave office is not something most politicians want attached to their name, even when colleagues privately agree it needs to happen.
Could a State Just Pass a Law to Fix This?
It’s a reasonable idea: what if a state said, “If our senator misses 50 votes in a row, we get to hold a special election”? Unfortunately, this almost certainly wouldn’t hold up. The Supreme Court ruled in a 1995 case, U.S. Term Limits v. Thornton, that states cannot add extra requirements for serving in Congress beyond what the Constitution already lists, like age and residency. A missed-vote rule would function as exactly that kind of extra requirement, just wearing a different disguise. A similar case from 1969, Powell v. McCormack, established that Congress itself can’t add requirements beyond what the Constitution states either.
States do have real power over how vacancies get filled once they exist — for example, whether a governor can appoint a temporary replacement. But they can’t invent a new way to create a vacancy in the first place. That power, weak as it is, sits only with the full Senate itself, through expulsion.
The Bottom Line
Whether the public learns about a lawmaker’s condition by accident, through a vague statement, or through complete transparency, the result is the same: nothing forces that person out of office except their own choice to leave, or a two-thirds vote that almost never happens. The Constitution assumes people will step down when they can no longer serve. It has no backup plan for when they don’t.
As the population of Congress keeps getting older, and cases like Granger, McConnell, and Mundt keep repeating, that gap in the system isn’t going away on its own.
