Trump dumps campaign manager

Donald Trump fired his embattled campaign manager, Corey Lewandowski, on Monday as the presumptive Republican presidential nominee struggled to pivot to the general election and his political operation became at times paralyzed by internal feuding. The dismissal of Lewandowski, a controversial Trump loyalist who chafed at suggestions that the candidate become more presidential, was seen as an urgent effort to calm Trump’s allies, donors and Republican Party officials who increasingly have been alarmed by a recent series of missteps and dramas. In March, Trump defended Lewandowski against charges that he assaulted a reporter at a campaign news conference in Florida/Washington Post. More here.

Question: Is this a sign of desperation? Or a good move, now that the nomination has been wrapped up?
