Sen. Susan Collins drew fresh scrutiny after a Fox News interview showed the 73-year-old Republican with a visible tremor, renewing questions about her fitness as she prepares for what may be the toughest reelection fight of her career.

The Maine senator, who first took office in 1997, was seen shaking on camera during the sit-down. A campaign advertisement from February also went viral earlier this week, with viewers noting trembling hands, a twitching head, and a quavering voice as Collins unboxed a pair of sneakers. In the ad, she quipped: "This is perfect for 2026 because I'm...running."

The footage circulated widely on X, where journalist Ken Klippenstein posted a pointed question directed at Fox News: "Have you asked why she's constantly shaking (including in this interview)? And if not, why not?" Other users piled on. One wrote, "She doesn't sound or look good here at all. Noticeable difference from years past." Another asked, "Why is she shaking uncontrollably? Why aren't you asking about her health? Is it preventing her from doing her job?"

Collins' visible tremor is not new. The Daily Mail reported that her shaking has been discussed following public appearances dating back to at least 2019. No cause for the tremor has been publicly disclosed, and Collins' office has not offered a medical explanation in any of the available reporting.

A seat Republicans cannot afford to lose

The health questions land at a politically precarious moment. Republicans are defending 22 Senate seats in November and fighting to protect a 53-47 majority. Collins' Maine seat is one of the contests that could tip the balance.

Collins herself projected confidence when asked about the race, telling Fox News, "I believe that will be the conclusion of Maine voters but obviously I don't take anything for granted." That careful phrasing suggests she knows the race will be competitive, and that her opponents smell an opening.

Her role as Senate Appropriations Chair makes the seat strategically important beyond raw numbers. Losing it would cost Republicans a senior committee gavel and weaken their hand in spending fights.

The political dynamics around Collins have grown more complicated. President Trump turned on her after a Venezuela war powers vote in January, urging voters to oust her and saying she "should never be elected to office again." That kind of intraparty friction gives Democrats a rare opening in a state where Collins has long outperformed the GOP brand.

Democrats field a far-left challenger

Collins' presumptive Democratic opponent is Graham Platner, who emerged as the party's nominee after Governor Janet Mills dropped out of the race. Platner has campaigned on being pro-LGBTQ, supporting Medicare for All, and ending foreign wars, a platform well to the left of the typical Maine voter.

At a town hall in Appleton on May 2, 2026, Platner made a striking promise. He told attendees that if he wins but Democrats fail to take the Senate majority, he would engage in direct confrontation with the administration.

"If we don't get the majority and things continue to get worse, I will promise you that I'm going to be arrested as a United States senator."

The Midcoast Villager reported that Platner promised "an element of activism" regardless of whether Democrats control the chamber. He also said he plans to make the Trump administration testify before Congress if Democrats retake the Senate.

That kind of rhetoric, a Senate candidate openly pledging to get himself arrested, would normally dominate the coverage of a competitive race. The fact that Collins' health is drawing more attention tells you something about how visible the tremor has become.

Platner himself has drawn controversy. Resurfaced comments have already cost him endorsements from within his own party, raising the question of whether Democrats nominated the strongest candidate they could have fielded in a genuinely winnable race.

The broader Senate map

Maine is one piece of a sprawling 2026 Senate battlefield where Republicans must hold ground across more than two dozen seats. U.S. senators serve six-year terms with no federal term limits, which means Collins, if she wins, would be serving into her early eighties by the time the next cycle arrives.

That timeline is worth considering. Voters are not wrong to weigh whether a candidate can serve a full term effectively. Collins has held her seat for nearly three decades, and her seniority carries real legislative weight. But seniority means nothing if a senator cannot physically perform the job.

No medical records, diagnoses, or physician statements regarding Collins' tremor appear in any of the available reporting. That silence is itself a choice. Voters in Maine will have to decide how much it matters, and Collins' team will have to decide whether stonewalling health questions is a sustainable strategy through November.

What remains unanswered

The cause of Collins' tremor has never been publicly explained. No one has reported when the shaking first began, only that it has been observed since at least 2019. Fox News, which conducted the interview, has not publicly addressed Klippenstein's question about whether the network asked Collins about her health.

Collins' recent legislative record shows an active senator still engaging on major votes. Whether that record is enough to quiet the health questions, or whether the video footage will define the race, is now the central tension in one of the most closely watched Senate contests in the country.

Maine voters deserve a straight answer. If Collins is fit to serve another six years, say so with evidence. If the question is too uncomfortable to address, voters will draw their own conclusions, and they should.
