FORT LAUDERDALE, FLA. >> A Florida prosecutor's office plans to hold a news conference amid reports that presidential candidate Donald Trump's campaign manager won't be prosecuted over a videotaped altercation with a female reporter.

A spokesman for Palm Beach County state attorney Dave Aronberg told The New York Times there will be a news conference Thursday but would not say what the news conference will be about.

Police in Jupiter, Florida, charged Corey Lewandowski with simple battery, a misdemeanor, last month.

The charge came after a video showed Lewandowski grabbing Michelle Fields, who worked for Breitbart News at the time, as she tried to ask Trump a question after a March 8 appearance. The video appears to show him yanking her backward.

Lewandowski has said he's innocent.

Corrects earlier version that incorrectly identified Dave Aronberg as the spokesman for the state attorney.
