There's some internal discord in Donald Trump's campaign team, with disagreements over who is advising the candidate and whether his current team must expand if he is to win the GOP nomination, sources within the team told NBC News.
The news comes after a significant loss in Wisconsin, where rival Ted Cruz won the primary.
After several tough weeks, peppered by charges against Trump's campaign manager for misdemeanor battery, and then comments from the candidate that infuriated all sides of the abortion debate, some within the Trump team said it was time for changes.
"There are essentially five or six people in the campaign," said one person who would only speak on the condition of anonymity. "Certain people don't want to lose power."

Speaking Tuesday with MSNBC, Trump said he had "not heard anything about inner fightings of the campaign. But you know we have a very successful campaign going and I think we're going to keep it going."
