Donald Trump has suggested that Speaker of the House Paul Ryan isn't supporting him in order to foster his own presidential campaign in 2020. When asked by ABC News' Tom Llamas before a campaign event tonight in Green Bay, Wisconsin, Trump responded, "Well, maybe not, because maybe he wants to run in four years or maybe he doesn't know how to win." Ryan has stopped campaigning for Trump after the leak of a 2005 tape in which Trump talks about groping women.
