Mr Lewandowski’s career has been dotted with controversy.
He was forced out in 2016 three months after being charged with battery for grabbing a reporter who was trying to question Trump.
Although the charges were dropped, Mr Lewandowski’s position became untenable when, according to reports in the US, Trump’s daughter Ivanka threatened to step away from the campaign unless he was sacked.
Brushes with the law
There have been other brushes with the law. In 2022, he was charged with a misdemeanour battery following allegations that he made unwanted advances to the wife of a Trump donor at a dinner.
Under a plea agreement, he paid a $1,000 fine, served 50 hours of community service and completed eight hours of counselling.
‘I think this is great’
However, the rehiring of Mr Lewandowski was welcomed by Trump supporters.
“He is a friend of mine, I think this is great,” Jeff Lord, a veteran Republican strategist who worked in the Reagan White House, told the Telegraph.
Mr Lord added: “I think Trump wants people around him who know him well, are seriously professional and have been through these campaigns before.
“This is another stage, we are in the last two-plus months of the campaign. You need everyone on board. This is what you spend years planning for.”
