UPDATE: 1:50 p.m. EDT — Speaking to CNN's Dana Bash Monday, just hours after he was fired, former Donald Trump campaign manager Corey Lewandowski praised his former boss and indicated he wasn't sure why he had lost his job. Lewandowski spoke calmly about his firing and called members of the Trump campaign his "friends." When asked if he had been escorted from Trump tower Monday morning, he said he had followed protocol and it "doesn't really work that way."

Lewandowski spent his time on CNN speaking highly of his former boss and his family. He said Trump will be the next president of the United States. He denied reports that he had been working to plant negative stories about Ivanka Trump's husband, Jared Kushner.

UPDATE: 12:45 p.m. EDT — Donald Trump's daughter, Ivanka Trump, reportedly played an important role in getting now-former campaign manager Corey Lewandowski fired Monday, according to several reports. Some reports indicate that Lewandowski may have been fired after he tried to plant negative stories about Ivanka Trump's husband, Jared Kushner, who has been playing an increasingly prominent role on the campaign trail.

Trump cut Lewandowski loose in the morning during a routine meeting for the campaign. 

Original Story — Corey Lewandowski, the campaign manager for Republican presidential candidate Donald Trump, is parting ways with the campaign, according to the New York Times. The decision to switch gears comes as Trump and his improbably successful campaign have faced increased scrutiny from allies and donors who are concerned about his pivot from Republican primary candidate to general election candidate.

“The Donald J. Trump Campaign for President, which has set a historic record in the Republican primary, having received almost 14 million votes, has today announced that Corey Lewandowski will no longer be working with the campaign,” Hope Hicks, Trump’s spokesperson, said in a statement. “The campaign is grateful to Corey for his hard work and dedication, and we wish him the best in the future.”

Lewandowski became well-known earlier this year when at a Trump rally he reportedly grabbed Michelle Fields, a journalist covering the campaign. She posted photos on social media allegedly showing bruising from when he grabbed her.

The fallout from that exchange was widely discussed in national media outlets. Fields, who then worked for the conservative media organization Breitbart, would later quit that job when the company — which was thought to be particularly fond of Trump — failed to provide the level of support she expected from her employer.

Lewandowski has refused to apologize to Fields, and the two continue to feud on Twitter. He has called her “delusional” for thinking that he had injured her. After Fields filed a police report, Lewandowski was arrested March 29. Video footage of the exchange confirmed that he grabbed her — alongside other reporters who were present and backed up Fields' claims. Lewandowski was eventually spared from charges when the attorney representing the county in Florida where the incident occurred declined to pursue the charges.

Fields has said the Trump campaign, in its response to her accusations, defamed her by calling her a liar.
