Presumptive Republican nominee Donald Trump is parting ways with his campaign manager Corey Lewandowski, according to the New York Times.

“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,” stated Hope Hicks, Trump’s campaign spokesperson. “The campaign is grateful to Corey for his hard work and dedication and we wish him the best in the future.”

“Mr. Trump had faced increasing concerns from allies and donors, as well as his children, about the next phase of the campaign as he pivots toward a general election,” the New York Times reported on Monday. “One person briefed on the moves, who asked not to be identified, said the campaign had long planned adjustments to adjust to the needs of a general election campaign.”
