It's just like calling homosexuals 'gays.' Gay means happy! You know, it's just to try to dilute it so that it becomes socially acceptable, and if you say anything against homosexual marriage or anything - 'Oh, you're not tolerant.'

Marco [Rubio] made reference earlier to the litigation against Trump University. It's fraud case.
