CNN: In an interview with CNN's Jake Tapper, Marco Rubio says he plans to attend the Republican convention, and will release his delegates to vote for Donald Trump to help him beat Hillary Clinton.
TAPPER: If Donald Trump asked you to speak on his behalf, you would do so?
RUBIO: Certainly, yeah. I want to be helpful. I don't want to be harmful because I don't want Hillary Clinton to be president. My policy differences with Donald Trump-- I've spent months talking about them, so I think they're understood.
