NBC's Katy Tur: 'Growing internal dissent' in Trump campaign fueled by racially charged comments

Aides of the presumptive Republican nominee Donald Trump's campaign are becoming increasingly agitated with the candidate's racially charged comments, according to NBC's Katy Tur.

The journalist joined MSNBC's Morning Joe on Monday, saying Trump "doesn't have much of a campaign. He hasn't grown since he got the nomination. The campaign is saying they are currently trying to grow the operation and they will be growing the operation."

Tur noted that aside from the Trump campaign's press secretary Hope Hicks, he doesn't really have much of a communications team.

"And there's growing internal dissent," Tur confirmed. "Absolutely. And for the first time, I'm hearing inside the campaign, the same things that I've been hearing outside the campaign -- especially with some of the more outrageous comments or controversial comments."

The billionaire businessman has come under fire after saying that Indiana-born Judge Gonzalo Curiel cannot fairly preside over lawsuits against Trump University because of his Mexican heritage.

High-profile Republicans have spoken out against Trump's racially charged remarks, and Tur says even staffers within his campaign are unhappy with them.

"I'm hearing aides say that this is extraordinarily frustrating to them, that they believe these are the sort of things that will end up sinking this campaign," she said. "The biggest hurdle right now is the candidate himself, because he says what he wants, no matter what they do behind the scenes."

The NBC correspondent said Trump aides feel as though "they can hire the best people if they could get them, but it doesn't ultimately matter, because Donald Trump will say what he wants."

Trump took to Twitter after Tur's appearance on MSNBC, tweeting:
