Jake Tapper asked Donald Trump if his judge attack was racist — then followed up 23 times

There's persistent ... and then there's Jake Tapper.

The CNN anchor posed the following question to Donald Trump on Friday:

Let me ask you about comments you made about the judge in the Trump University case. You said that you thought it was a conflict of interest that he was the judge because he is of Mexican heritage, even though he is from Indiana. Hillary Clinton said that that is a racist attack on a federal judge.
