CNN reported hours after Corey Lewandowski's dismissal as Trump's campaign manager that Ivanka Trump had come to her father to argue for his firing.

Ivanka Trump was angry, CNN said, that Lewandowski had sought to plant negative stories about her husband, Jared Kushner, who is working on Donald Trump's transition team.

She told her father he had to choose between letting Lewandowski go or moving forward with the campaign without her, CNN said.

Lewandowski had been a lightning rod of controversy both from inside and outside the campaign. Most notably, he was charged with battery after he grabbed the arm of a former Breitbart News reporter as she was trying to ask Trump a question after a press conference in Florida.

Those charges were eventually dropped, but NBC reports that the incident prompted Ivanka to press her father to make a change, though it took until Monday to convince him.
