WASHINGTON: Republican presidential hopeful Donald Trump dumped his controversial campaign manager on Monday (Tuesday in Manila), as he looked to revitalize a White House bid after recent stumbles ahead of a November showdown with Hillary Clinton. Trump, 70, has taken a hit in the national polls of late and sparked outrage with comments about Muslims in the wake of the Orlando gay club massacre. With less than a month to go before the Republican convention, changes were inevitable. After weeks of rumors about dissent within his camp over how best to take on Clinton, the presumptive Democratic nominee, the hammer came down when campaign manager Corey Lewandowski left Team Trump. “I think Corey is terrific,” Trump told Fox News. “I think it’s time now for a different kind of a campaign. We ran a small, beautiful, well-unified campaign… I have 73 people. Hillary Clinton has almost 900 people and we’re in the same position.” Trump said he planned on announcing his pick for vice president at the Republican convention in Cleveland next month.
