The Republican National Committee scrapped plans to praise Donald Trump's immigration speech Thursday after the nominee slammed illegals and even suggested deporting Democrat Hillary Clinton, according to news reports.

But both RNC Chairman Reince Priebus and the Trump denied to The New York Times that the relationship between the parties was strained.

Priebus described it as a "fantastic working relationship" in a statement.

"Any insinuation to the contrary is purely overblown gossip," he added.

Jason Miller, a Trump spokesman, said: "Cooperation between the Trump campaign and the RNC has never been better — we are fully integrated.

"Everybody knows what has to be done to elect Mr. Trump and stop Hillary Clinton," he told the Times.

However, six senior Republicans cited the Arizona move as an example of how the relationship between the committee and its nominee has "grown strained over the last month," according to the report.

These Republicans have "detailed knowledge of both groups, some of whom asked to speak anonymously for fear of exacerbating tensions," the Times reports.

Since both sides rely on a joint fundraising agreement, a full-scale break is not likely — but any rift could "threaten … the party’s ability to work smoothly with Mr. Trump during the most critical post-Labor Day phase of the race," according to the article.

In one instance, Stephen Miller, Trump’s senior policy adviser, slammed Priebus in an email to campaign staffers after several members of the National Hispanic Advisory Council for Trump resigned after the nominee's speech in Phoenix.

"The RNC needs to take control of this situation and quickly," Miller wrote, the Times reports.

He called the departing advisory council members "professional amnesty lobbyists," before asking, "Can Reince do his job?"

Within the RNC, officials "have lost confidence in Mr. Trump’s ability to right his listing campaign," the senior Republicans told the Times.

They complain of divisive power struggles between top advisers and Trump family members — and noted that the nominee has now installed the third leadership team of his campaign.

Priebus, whom the Times reports has a "warm" relationship with Trump — "and speaks with him daily" — has told some of the Republicans that he has been "disappointed" at the candidate's inability "to evolve as a candidate in the general election."

But the chairman denied making such statements.

"I’ve said exactly the opposite," Priebus told the Times. "I think he’s had his best three weeks."
