A California winery owner is in a trademark dispute involving former President Donald Trump, according to reports. The dispute centers on a wine product described as “45-47 Republican Red Special Edition,” associated with the winery’s owner, Paul Johnson. The reporting says Trump is seeking to prevent or limit use of the label, framing the matter as part of a broader conflict over branding connected to Trump and Republican themes. The winery owner’s use of the product name and related labeling is presented as the point of disagreement, with the case focused on trademark rights rather than the wine itself. The sources describe the situation as causing tension among Trump-aligned supporters, but the core factual claims across outlets are that a specific named wine label is contested and that a trademark dispute is ongoing between the winery owner and Trump or entities connected to him. No final legal outcome is reported in the provided summaries.
