Sen. Roger Marshall of Kansas and Democratic challenger Adam Hamilton traded sharp criticisms regarding President Donald Trump, immigration enforcement and transgender athletes during a Wednesday night debate. The one-hour contest occurred less than two weeks before Election Day, with Marshall seeking a second term and Hamilton attempting to become the first Democrat elected to the U.S. Senate from Kansas since 1932. The race has attracted national attention as both parties compete for control of the Senate, a dynamic highlighted by Trump's recent campaign trip to the state.

The debate opened with personal controversies facing both candidates. A New York Times review cited by moderators noted that Marshall's former medical practice sued more than 700 patients over unpaid bills. Marshall defended the practice's actions by citing financial obligations, including a mortgage, electric bills and payroll for 300 employees, while noting the practice also provided $3 to $4 million in charity annually. Hamilton faced questions about his handling of sexual abuse allegations involving a volunteer at his church's summer camp. He acknowledged it was a mistake not to ensure the individual did not return to the camp following an initial investigation.

Trump became a central figure when moderators played footage from his campaign appearance for Marshall earlier in the week. In the clip, Trump asked the crowd to "pretend" he was on the ballot. When asked if Trump's support meant he would back every part of the president's agenda, Marshall answered "no," stating he had objected to Trump multiple times. He specifically cited disagreements over recent immigration enforcement in southwest Kansas and Trump's approach to beef imports. Despite these differences, Marshall urged Trump voters to support him, warning that electing Hamilton could help Democrats capture the Senate.

The candidates aligned on the question of gender identity but diverged on the regulation of transgender athletes. Both stated there are two genders. Marshall noted he delivered 5,000 babies during his medical career, observing that almost half were boys and half were girls. Hamilton agreed, stating there are two genders: male and female. On sports eligibility, Hamilton argued that biological males should not compete against females, citing his 12-year-old granddaughter and describing such competition as unfair. Marshall countered that boys should be in boys' sports and girls in girls' sports by high school, accusing national Democrats of pushing "transgender ideology." Hamilton later accused Marshall of using the issue to bully people.

The discussion turned to artificial intelligence, where Hamilton called for federal oversight comparable to the Nuclear Regulatory Commission. However, when pressed to identify specific regulations he would support, Hamilton admitted he did not yet have an answer, noting that experts are still struggling to understand the technology's dangers. He described AI as a potential existential threat to the human race. Marshall advocated for a "light touch" approach focused on national security, transparency and privacy protection.

Hamilton sought to distinguish himself from former President Joe Biden when challenged over his claim to "lead from the middle." Pointing to Hamilton's past donations to Biden, former Vice President Kamala Harris and Rep. Sharice Davids of Kansas, moderators asked him to identify a progressive policy he opposed. Hamilton called Biden's border policies a disaster and affirmed his belief in strong and secure borders. He added that he does not favor the Socialist Party and would not support Senate Minority Leader Chuck Schumer for majority leader if Democrats gain control of the chamber.
