Trump did not react angrily to what Lewandowski said and instead listened and watched for the reaction of others, revealing little about where exactly he lands in these debates among Trump associates, the people added.
But essentially, Lewandowski tried to convince the president that "he wasn't being served well," in the words of one person with knowledge.
While Trump did not signal whether he would act on Lewandowski's suggestions, some White House aides bristled at the outside adviser's attempt to steer the political strategy. Later, outside the Oval Office, Stepien and Lewandowski had a "very intense" conversation about the broader political operation and what some aides see as Lewandowski's meddling in it from the outside, while Lewandowski questioned Stepien's performance, according to advisers with knowledge. The men were later spotted by other aides continuing to argue outside.
A White House spokeswoman declined to comment.
The meeting, and the fights, underscore the tension surrounding the president's political operation - and the occasional chaos that arises even as Kelly has tried to impose more order. Advisers like Lewandowski and former White House chief strategist Stephen Bannon, now at Breitbart News, continue to talk to the president, who likes them personally, even as other advisers try to keep them away.
There are also strains inside the White House between the political affairs team, the RNC and some of his closest counselors on the outside - and they are all competing for Trump's ear, the people said, requesting anonymity to speak candidly about private conversations.
There were points of unity in the meeting. All sides of Trump's orbit are hoping the recently passed Republican tax bill becomes more popular in upcoming months, and that the federal Russia probe dies down. Trump made clear to his advisers that he wants to be heavily involved in the upcoming elections, although it is unclear how many places will welcome a presidential visit.
Trump's reaction to the meeting could play out in the coming days and weeks while he is away at his Mar-a-Lago resort in Florida, advisers said. But with 2018 and its stakes frequently on his mind, changes of either personnel or strategy are possible, the people said.
One White House official briefed on Trump's lunch with former chief of staff Reince Priebus Tuesday said they mainly strategized on 2018, and Priebus gave the president warnings about the electoral landscape. Afterwards, Trump told others that Priebus expressed concerns about the midterms. Priebus couldn't be reached for comment.
Kelly has occasionally griped about the RNC and its chairwoman, Ronna McDaniel, advisers say. A number of senior advisers in the White House say the RNC is not doing enough to defend the president and that its communications and political operation need to be improved - with more Trump loyalists installed. Meanwhile, they complain that Bob Paduchik, a Trump ally at the RNC, has suffered slights there.
In turn, the RNC often finds itself at the whims of a president that can reverse on a dime, like he did on the Alabama Senate election. McDaniel has told officials at the RNC that her members are sometimes at odds with the White House. The RNC was particularly frustrated by Alabama, where Trump agreed for the group to pull out of supporting Roy Moore's campaign but then backed Moore and forced the RNC to reverse its stance.
Several White House officials say they don't expect major changes at the RNC, and that Trump continues to praise McDaniel in private. But there is talk of putting more Trump people at the organization or trying to take on more control.
An RNC spokeswoman didn't immediately respond to a request for comment.
