Florida prosecutors will announce Thursday whether they plan to prosecute Donald Trump's campaign manager, Corey Lewandowski, on a battery charge in connection with former Breitbart News Network reporter Michelle Fields, Fields said Wednesday.

Politico, citing multiple sources whom it didn't identify, reported Wednesday that Palm Beach County State Attorney Dave Aronberg will announce Thursday that he won't pursue the charge.

Lewandowski, 42, turned himself in to Jupiter police on a charge of simple battery after he was accused of having grabbed and bruised Fields' arm when she tried to question Trump at a campaign event on March 8.

Lewandowski initially said he never touched Fields, but video released by police showed that he did make contact with her.

Fields said on Twitter on Wednesday that Aronberg's office told her that the decision whether to go forward with the case would be announced Thursday.

Fields said that the prosecutor's office called her two weeks ago and that she agreed to a deal in which Lewandowski would issue her an apology. She said she hadn't heard back about the arrangement, and a source familiar with the situation told NBC News that it wasn't clear whether Lewandowski had accepted the proposal.

Fields and three of her colleagues resigned from Breitbart, a prominent force in conservative politics, after the site published an account questioning Fields' allegations. "I can't stand with an organization that won't stand by me," she said at the time.

Lewandowski remains campaign manager, but it's unclear whether he retains control over the Trump operation after
