Just days before Donald Trump's campaign manager was charged with battery after he was captured on videotape grabbing a female reporter, an executive with Trump's hotel company was charged with assault for allegedly throwing a mother of two to the pavement at his ritzy Brooklyn condo.

The executive, Nathan Crisp, 34, was hit with the charge after the Easter Sunday confrontation with Sheneik McCallum, 27. McCallum, who is African American, had pulled into the parking garage at the condo complex where Crisp lives to check one of her children's car seats, she told the New York Daily News.

She had her kids, Justin, eight, and Raquel, four, in the car, along with a four-year-old niece. That's when Crisp, also in a car, pulled up behind her, apparently impatient to exit the garage. He yelled at her to get off the private property, adding: "You need to move," she recounted. "I don't know if he was drunk, or under any type of drug, but he was very aggressive from the start."

When the two confronted each other outside of their cars McCallum threatened to call the police. That's when "he grabbed me," she told the News. "He got infuriated. We started tussling and he ended up picking me up and body slamming me to the floor — not once but twice. I could have broken my back."

She hit her head and suffered scratches and bruises on her feet, according to police, reported the New York Post. Crisp was taken into custody a short time later and was given a desk appearance ticket requiring him to return to court to answer the charge against him in early May.

Crisp insisted that he is completely innocent of any assault. "I am totally innocent of all charges and look forward to defending this matter in court at which time I am confident that I will be fully vindicated," he wrote to the Daily News. "I do not have any further comment."

A spokeswoman for Crisp's employer, Trump Hotels, said it was a "personal matter," but that the organisation would conduct its own investigation. Crisp is the vice president for revenue management at the company, according to his LinkedIn page. "Trump Hotels takes these allegations seriously," the spokeswoman said.

Trump's campaign manager Corey Lewandowski was hit with a misdemeanor battery charge after police released a video showing him grabbing the arm of reporter Michelle Fields and yanking her away from Trump as the journalist was asking the candidate questions.

After Fields complained, Lewandowski posted a tweet, saying: "Michelle Fields you are totally delusional. I never touched you. As a matter of fact, I have never even met you."
