A singer and stark Trump supporter filed a sexual assault complaint against the president's former campaign manager for hitting her on the butt during a Washington gathering in November.

Joy Villa, a potential congressional candidate who wore a 'Make America Great Again' gown at the Grammys this year, announced Tuesday that she plans to meet with detectives in the capital next week to discuss the complaint against Corey Lewandowski.

Villa said she was initially reluctant to come forward because she was worried about any backlash.

She said she finally decided to call Washington's Metropolitan Police Department on Christmas eve after a friend who witnessed the incident spoke about it publicly and other friends urged her to come forward.

'I didn't know him at all,' Villa said about Lewandowski.

'I only knew him by reputation. He broke my trust.'

The 26-year old said she saw him at a gathering at the Trump International Hotel on the day after Thanksgiving, and said Lewandowski struck her 'extremely hard' even after she told him to stop.

She said she felt it was 'disgusting and shocking and demeaning.'

Villa, who is considering a run for a Florida congressional seat, said she initially thought it was sexual harassment, but police told her that touching someone on any body part that is sexual in nature constituted sexual assault.

She said she was told it was classified as a misdemeanor.

'I was initially fearful to come forward with this,' she said, adding that she did not want to bring shame or embarrassment on Lewandowski's family or hers.

'I did nothing wrong,' Villa said.

'I realized if he's not going to respond or apologize to me, I think it's the right thing to do.'

Lewandowski did not respond to an email seeking comment.

Trump fired Lewandowski as campaign manager in June 2016. He has since written a book about the President, titled 'Let Trump be Trump!,' in which he talks about being on the campaign trail with the now president

Villa made news earlier this year when she wore a dress displaying Trump's campaign slogan at the Grammys.

She explained her decision to wear the dress in an Instagram post, writing, 'You can either stand for what you believe in or fall for what you don't.

'Agree to disagree.'

This is not the first time Lewandowski has faced police charges.

In March 2016 he was charged with misdemeanor battery for an altercation involving a female reporter after a news conference in Florida. The charges were later dropped.

Trump fired him as campaign manager in June 2016.

He has since written a book about the President, titled 'Let Trump be Trump!,' in which he talks about being on the campaign trail with the now president.

Lewandowski is the individual who divulged that every day on the trail the president would have a meal of two big macs, two filet-o-fish's and a milkshake from McDonalds.
