Mr. Lewandowski could not immediately be reached for comment about his departure, which was announced by the campaign.
“The Donald J. Trump Campaign for President, which has set a historic record in the Republican primary having received almost 14 million votes, has today announced that Corey Lewandowski will no longer be working with the campaign,” the campaign spokeswoman, Hope Hicks, said in a statement. “The campaign is grateful to Corey for his hard work and dedication and we wish him the best in the future.”
With the Republican National Convention looming next month, Mr. Trump is facing the task of broadening his team to include people with previous presidential campaign experience. Mr. Trump also has been turning his attention to fund-raising for the first time, a task that Mr. Lewandowski had assumed oversight of and one that has gone slowly for the campaign. The campaign has aired no ads in the general election and there has been no “super PAC” that received a clear public blessing from Mr. Trump and his top advisers.
The loss of Mr. Lewandowski was intended as part of a larger shift toward the final sprint of the race, according to those briefed on the matter.
Mr. Trump had faced increasing concerns from allies and donors, as well as his children, about the next phase of the campaign. It is a move that could reassure donors and Republicans more broadly that he can adjust toward a November election strategy.
Two people briefed on the move, who spoke on condition of anonymity, said that Mr. Lewandowski was fired.
The campaign manager was seen as having a hostile relationship with many members of the national press corps who cover Mr. Trump, and many officials at the Republican National Committee had strained relationships with him.
Mr. Lewandowski was said to have resisted certain moves that would have increased the number of staff members, at times blocking Mr. Manafort from making hires or later undoing them.
But the people briefed on Mr. Lewandowski’s departure said that the circumstances went well beyond any particular episode or any particular relationship. Mr. Lewandowski had a penchant for making headlines about himself that overshadowed his boss, including being charged with misdemeanor battery, a charge later dropped, after he was accused of grabbing a reporter as she approached Mr. Trump with a question in Jupiter, Fla., on March 8, a night when the candidate won three of four Republican state primary votes.
One person stressed that the move had been in the works for many weeks, particularly since it became clear that Mr. Trump would be the nominee. The person added said that the campaign is now focusing on bringing the party together, including hiring new staff members and adjusting to the race against Hillary Clinton. And there had been a desire for many weeks to make changes ahead of the Republican National Convention, July 18-21 in Cleveland.
Mr. Lewandowski, 42, a New Hampshire resident with deep ties to the state, had made himself a delegate to the convention months ago. He is still the chairman of the state’s delegation to the convention.
No one inside the campaign was given any advance warning about the dismissal of Mr. Lewandowski, who was on the campaign’s daily 8:30 a.m. conference call on Monday, according to a person briefed on the developments.
On Twitter, some campaign staff members rejoiced at the news of Mr. Lewandowski’s departure.
“Ding dong the witch is dead!” wrote Michael Caputo, a Trump communications aide who was said to have been antagonized by Mr. Lewandowski.

enVolve note: Well, I hope this opens up much better things for the Trump campaign. Corey has been controversial for a long time and maybe it has finally caught up with him. We shall see in the upcoming months whether this will hurt or help the Trump Campaign.
