Donald Trump’s abrupt decision to fire his campaign manager Corey Lewandowski reportedly came at the request of his own children, who were irritated with the senior staffer’s constant bickering with others involved in their father’s campaign.

According to CNN, Lewandowski’s dismissal Monday morning came less than 24 hours after Ivanka Trump advised her father that she would no longer assist him in his bid for the White House if he didn’t immediately axe his campaign manager.
