WASHINGTON - A singer and potential congressional candidate said Tuesday that she has filed a sexual assault complaint against President Donald Trump's former campaign manager for hitting her twice on her buttocks during a Washington gathering in November. Joy Villa, a Trump backer who wore a "Make America Great Again" dress at the Grammys this year, said she plans to meet with detectives in Washington next week about the complaint against Corey Lewandowski. In a phone interview from Tampa, Fla., Villa said she was initially reluctant to come forward because she was worried about any backlash.
