The statement is overwhelmingly supported by all ten provided primary sources. A wide range of highly authoritative and credible news organizations, including PBS, CBS, Reuters, The New York Times, and CNN, uniformly report that Donald Trump proposed or called for a 10% cap on credit card interest rates. The consistency across every single source is exceptionally strong, with no conflicting or contradictory evidence presented. Several sources add the specific detail that the proposed cap was for a one-year period, which is a clarification rather than a contradiction of the core claim. The sheer volume, high authority, and complete unanimity of the evidence provide the highest possible confidence in the statement's truthfulness.
