The provided article text does not contain any actual reporting on this story. What was supplied is only the Daily Mail's page furniture — site navigation, the masthead and weather widget, and a long list of unrelated headlines from elsewhere on the site (covering topics such as a French murder case, the World Cup, and celebrity news) — rather than the body copy of the piece about GOP senators and a "Trump-themed midterm convention".

As a result, no details, quotes, numbers or context about the alleged convention or the senators' comments can be accurately reported. A reliable summary would require the actual article text to be retrieved from the source.
