Top Republicans who have stood by Donald Trump for months have lost their patience and are reportedly considering an intervention to set the GOP presidential nominee and his campaign back on track before it's too late.

Party chief Reince Priebus, former House Speaker Newt Gingrich and former New York City Mayor Rudy Giuliani plan to convince Trump once and for all that he needs to stick to his message and avoid going off-script if he wishes to maintain the GOP's support and be competitive against Hillary Clinton.

According to NBC News, the trio of influential Republicans is looking to work with Trump's adult children — Ivanka, Eric and Donald Jr. — as well as his senior advisers to "reset" the billionaire's campaign before he ruins his chances to make inroads with undecided voters before the upcoming presidential debates or self-destructs.

None of the three GOP kingmakers returned the Washington Examiner's requests for comment. A spokesman for the Republican National Committee said he had "no clue" whether Priebus has been discussing a possible intervention with other Trump allies.

Talk of a possible intervention first emerged on Wednesday, less than 24 hours after Trump left Republican leaders dismayed after he declined to endorse House Speaker Paul Ryan ahead of his primary.

Contributing to GOP leader's growing concerns is the latest controversy Trump has refused to let go of, which began last week when he criticized Khizr Khan, the father of a fallen Muslim-American soldier who spoke out against him at the Democratic National Convention.

Some of Trump's staffers were rumored to be "suicidal" as of Tuesday night, shortly before the candidate gave an interview to Fox News' Bill O'Reilly in which he once again pushed back against Khan's "vicious" attacks.

Trump campaign chairman Paul Manafort denied reports on Wednesday that trouble has been brewing between the Republican nominee and party leaders, telling Fox News: "The campaign is moving forward in a positive way. The only need we have for an intervention is maybe with some media types who keep saying things that aren't true."

Seth Weathers, the former state director for Trump's Georgia campaign and a continued supporter of the businessman, said "nothing has changed" in Trump's inner circle despite the "tense few weeks" the candidate has faced.

"I think there's definitely a need for him to get back on message, on target with things, but I know a lot of people in the campaign who I'm in constant conversation with and none of the those who I'm talking to are even remotely alluding to [being suicidal]," Weathers told the Examiner.

"I'm sure they found someone to be the darling of the press and to say some s—t on background, but I'm not hearing that at all," he added, referring to the Manafort ally who anonymously told CNBC's John Harwood that Trump's staff was overwhelmed by what has recently transpired.

Trump himself pushed back against rumors of tension within his own campaign and with the GOP, tweeting Wednesday morning that "there is great unity in my campaign, perhaps greater than ever before."
