President Donald Trump dismissed a question about whether payments to Americans were intended to influence midterm voters, instead touting economic growth and tariff policy as Republicans confront voter frustration over healthcare costs. His administration is providing one-time $90 rebates to more than 20 million eligible original Medicare Part B enrollees at a cost of about $2 billion, while Trump has pledged a $5,000 dividend to every adult citizen if Republicans retain control of Congress. The administration has also begun mailing $500 Affordable Care Act refund checks to about 1 million people in 30 states whom it says were overcharged. Medicare Advantage enrollees, Medicaid premium-assistance recipients and beneficiaries paying income-related premiums are excluded from the rebates. Republicans hold slim majorities in both chambers, and critics have questioned the payments and dividend proposal amid national debt exceeding $40.2 trillion.
