In all, Tapper made an astounding 23 follow-up attempts. This moment right here — with this look on Tapper's face — perfectly encapsulates the exchange.
Tapper's relentlessness ultimately paid off. He finally got a straight answer out of the presumptive Republican presidential nominee.
TAPPER: If you are saying he cannot do his job because of his race, is that not the definition of racism?TRUMP: No, I don't think so at all.
Tapper presumably had other subjects he would have liked to get to. Trump likely figured as much and assumed he could stall long enough for his interviewer to move on. That's usually how it goes.
But Tapper refused to drop the subject until Trump offered a yes-or-no answer. It was clearly an exhausting effort. But it showed that even Donald J. Trump can be worn down by a journalist who never gives up.
