Spicer said that Trump kept defying the odds only to face a new narrative,
"He keeps getting told what he can't do by this narrative that's out there. And exceeds it every single time. And I think there's an overall frustration when you turn on the television over and over again and get told that there's this narrative that you didn't win, you weren't going to run, you can't pick up this state," he said. "Over and over again there's this constant attempt to undermine his credibility and the movement that he represents. And it's frustrating for not just him, but I think so many of us that are trying to work to get this message out."
Spicer said that this is "demoralizing" for Trump.
The press secretary also argued that the media's treatment of Trump was unprecedented.
"I've never seen it like this," Spicer said.
