Former Patient Files Class-Action Suit Over Senator Marshall’s 18% Interest Rates

Key points

• Meischa Zimmerman, a former patient, filed a class-action lawsuit in Kansas state court against Senator Roger Marshall and his former practice, Heartland OBGYN.
• The lawsuit contends that Marshall’s practice charged an 18% annual interest rate on unpaid medical bills, a rate described as 'egregious' and potentially illegal under state laws that typically cap medical interest at 15%.
• The Kansas City Star reported that an analysis of roughly 150 medical practices found no other providers charging rates above 12%, making Marshall’s 18% rate the highest in the state.
• Zimmerman was sued in 2009 for $3,596 related to a cesarean section delivery and was arrested three times for missing court dates, including once while eight months pregnant.
• The New York Times previously reported that Marshall sued more than 700 patients, with at least 81 facing arrest for missing court dates.
• The lawsuit coincides with a tight 2026 Senate race in Kansas, where Marshall is trailing or tied with Democrat Adam Hamilton in recent polls.

Background

This lawsuit follows a series of controversies involving Senator Marshall’s medical debt collection practices. In October 2026, fact-checkers and the ADL condemned President Trump’s defense of Marshall’s actions, which included an antisemitic slur. Prior to that, internal polls in early October showed Marshall trailing Hamilton, with voter anger over his history of suing patients driving his declining favorability. The Kansas Senate race, previously considered a safe Republican seat, has become a toss-up due to these issues.

How outlets are covering it

The New York Times focuses on the legal details of the class-action lawsuit, emphasizing the 18% interest rate and the historical pattern of suing over 700 patients, including 81 who were arrested. MS NOW contextualizes the lawsuit within the broader 2026 Senate race, arguing that the debt collection practices were the turning point in the race, shifting polls in favor of Adam Hamilton. MS NOW also highlights the Kansas City Star’s investigation, which confirmed that Marshall’s 18% rate was the highest among reviewed practices and that his office was responsible for setting the rate. Both sources agree on the core facts but differ in emphasis: The Times highlights the legal and historical aspects, while MS NOW focuses on the political impact and the competitive nature of the race.

Why it matters

The class-action lawsuit adds a new legal dimension to the controversies surrounding Senator Roger Marshall, potentially affecting his re-election prospects in a previously safe Republican state. The alleged illegal interest rates and aggressive collection tactics have fueled voter backlash, contributing to a competitive race with Democrat Adam Hamilton. This case underscores the political consequences of a senator’s pre-political business practices and the impact of media investigations on electoral outcomes.

What to watch

The outcome of the class-action lawsuit could have significant legal and political implications for Senator Marshall. If the court rules against him, it may further damage his reputation and electoral chances. The race between Marshall and Adam Hamilton is expected to remain competitive, with the lawsuit and related controversies likely to be central issues in the final weeks of the campaign. Additional patients may join the lawsuit, and Marshall’s campaign may respond to the allegations in the coming days.
