Lewandowski out as Trump campaign manager

NEW YORK (AP) — Donald Trump fired his hard-charging campaign manager, Corey Lewandowski, on Monday in a dramatic shake-up designed to calm panicked Republican leaders and reverse one of the most tumultuous stretches of Trump's unconventional White House bid.

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