Donald Trump forces his campaign manager out

Mr Lewandowski — in some ways as brash and unconventional as the candidate himself — had been by Mr Trump’s side since the beginning of his unlikely rise to presumptive Republican nominee.
But he clashed with longtime operatives brought in to make the campaign more professional. He played a central role in daily operations, fundraising, and Mr Trump’s search for a running mate, but Mr Lewandowski’s aggressive approach also fuelled near-constant campaign infighting that complicated Mr Trump’s shift toward the general election.
