They are referring to what Rudy said. Read the whole article.
"Rudy Giuliani on Friday morning criticized MLB players who took a knee in protest of racial inequality during the National Anthem on Opening Day Thursday night. The former New York mayor specifically blasted the Yankees."
whats the word "who" referring to? Its msn stating the fact to which rudy is criticizing.
dont say that it means rudy was blasting those players "who" took a knee etc. bc it says he specifically blasted the yankees, none of which kneeled during the anthem rather before it.
grammer police please 👮♂️ (without the riot gear though)
