What Randall should have said

"Mr. Trump, I have already laid out the reasons why I feel Rebecca is not qualified to be your Apprentice.  I stand by those reasons, and I would not hire her."

Instead, he comes across as a preening jackass who's afraid that somebody is going to yank his moment in the sun away from him (if not, you know, out perform him again).  I can only imagine that he is already getting his first yelling at from The Donald, along the lines of "PLAY ALONG WITH THE SCRIPT AND DON'T EVER SECOND GUESS ME, OR YOU'LL BE THE FIRST APPRENTI THAT I FIRE BEFORE THEIR YEAR IS UP!"
