Who is Donald Trump's campaign manager Corey Lewandowski? Who is Donald Trump's former campaign manager Corey Lewandowski?
(3 months later)
Corey Lewandowski - the brains behind Donald Trump's unlikely yet wildly successful presidential campaign - may be as brash and unapologetic as his boss. Corey Lewandowski - the brains behind Donald Trump's unlikely yet wildly successful presidential campaign - was perhaps as brash and unapologetic as his boss.
While Trump's pugnacious style may have made him a front-runner, Lewandowski's rough edges have led to legal trouble for the campaign manager. While Mr Trump's pugnacious style made him the front-runner, Mr Lewandowski's rough edges led to legal trouble for the campaign manager.
The 42-year-old Massachusetts native and former lobbyist was charged with simple assault, accused of grabbing a reporter's arm at a campaign event. The 42-year-old's departure was announced on 20 June, with speculation it was to adapt the campaign to a run for the White House.
He has denied reporter Michelle Field's allegations and said he will plead not guilty. Mr Trump had previously told the Wall Street Journal he had "tremendous energy" and a "wonderful vision for politics".
He had his start in politics in the mid 1990s after attending the University of Massachusetts and American University, working for several Republican congressmen. Friction with the media
Mr Lewandowski had a fractious relationship with the press.
Earlier this year, he was charged with battery after allegedly yanking a female reporter, Michelle Fields, out of Mr Trump's way after a campaign event.
Mr Trump defended him throughout that incident, which concluded when the charges were dropped.
"They've really hurt a very good person... I don't discard people... I told him he should never settle this case," Mr Trump said at the time.
Mr Lewandowski tweeted shortly after the alleged assault that he had never met Ms Fields, much less touched her.
That was not the only physical altercation he was linked to - on 19 March, video appeared to show him grabbing a protester by his shirt collar during an Arizona rally.
There were also allegations that Mr Lewandowski had been sexually inappropriate in tone to female reporters during his work for Mr Trump and in a previous job, according to a lengthy report in Politico.
Office politics
However Mr Lewandowski, who is married with four children, was scarcely more popular with the rest of Trump's campaign team.
One Trump campaign director, Michael Caputo, tweeted "Ding dong the witch is dead" following the news he was leaving.
Lewandowski also did not get along with Trump chief strategist Paul Manafort either and blocked him from hiring staff, the New York Times reported.
And he is said to have had a fractious relationship with Trump's press secretary, Hope Hicks, and once rowed publicly with her on a New York street, according to US media.
Politico's report said Trump campaign members at one point planned to deliver a letter to the presidential candidate's head of security, expressing concern about Mr Lewandowski's behaviour.
However, the plan was scrapped after Mr Trump won both the South Carolina and Nevada primaries.
Others complained about his alleged hot temper and use of profanity.
Taking a gun to work
The Massachusetts native and former lobbyist had also courted controversy in earlier jobs.
While working for Ohio Congressman Bob Ney in 1999, he was arrested after he brought a pistol into a congressional office building. He later said he brought the gun by mistake.While working for Ohio Congressman Bob Ney in 1999, he was arrested after he brought a pistol into a congressional office building. He later said he brought the gun by mistake.
Mr Lewandowski worked for the Republican National Committee, according to his LinkedIn page, and was a lobbyist for almost eight years. Mr Lewandowski also worked for the Republican National Committee, according to his LinkedIn page, and was later employed by Americans for Prosperity, a conservative advocacy group founded by billionaire conservative activist David Koch.
Most recently before working for Mr Trump, he was employed by Americans for Prosperity, a conservative advocacy group founded by billionaire conservative activist David Koch.
"Corey has tremendous energy, a wonderful vision for politics and the greatest candidate ever, without which none of it works," Mr Trump told the Wall Street Journal before the Republican primary in South Carolina.
The newspaper characterises Mr Lewandowski, who is married with four children, as "brash and ambitious" and that he "demands loyalty" and "subsists on little sleep".
His brush with Ms Fields - who at the time worked for Breitbart News - is not the only time he has been linked to a physical altercation on the campaign trail.
On 19 March, video appeared to show Mr Lewandowski grabbing a protester by his shirt collar during an Arizona rally.
In both his previous job with Americans for Prosperity and his time on the Trump campaign, there have been complaints about him being abrasive with reporters and sexually inappropriate in tone to female reporters especially, and quick to demonise colleagues who challenged him, according to a lengthy report in Politico.
According to that report, Trump campaign members had planned to deliver a letter to the presidential candidate's head of security, expressing concern about Mr Lewandowski's behaviour.
After Mr Trump won both the South Carolina and Nevada primaries, the plan was scrapped.
Others have complained about his alleged hot temper and use of profanity.
Mr Trump has defended his campaign manager, calling him a "great guy" shortly after the incident and tweeting that video footage of the alleged assault shows "nothing".
Mr Lewandowski tweeted shortly after the alleged assault that he had never met Ms Fields, who ended up resigning from her job over the scuffle, much less touched her.
"Mr Lewandowksi is absolutely innocent of this charge," a Trump statement said following the news of his arrest. "He is completely confident that he will be exonerated."
Speaking with reporters on Tuesday, Mr Trump defended Mr Lewandowski again.
"They've really hurt a very good person... I don't discard people... I told him he should never settle this case," he said.
