Lewandowski turned himself in to Jupiter police just after 8 a.m., according to a police report.
Surveillance footage captured at Trump National, off Donald Ross Road, corroborates Fields’ claim, the arrest report says.
Fields, who Tweeted photos of bruises on her arm she said resulted from the battery, resigned from Breitbart less than a week after the incident. She cited Breitbart's refusal to stand behind her amid the allegations as her reason for leaving.
Lewandowski replied to Fields' Tweet, writing: "You are totally delusional. I never touched you. As a matter of fact, I have never even met you."
Ben Shapiro, former Breitbart editor-at-large, also resigned, claiming in a prepared statement that the conservative news outlet, seen largely as supportive of Trump’s presidential bid, “abandoned” Fields “in order to protect Trump’s bully campaign manager.”
Several other employees followed suit in the following weeks and resigned, according to multiple reports.
New video of the incident has been released by authorities.
The Trump campaign has responded to the arrest.
