A Florida prosecutor has decided not to prosecute Donald Trump’s campaign manager Corey Lewandowski for battery after a March run-in with former Breitbart reporter Michelle Fields, Politico reported on Wednesday, citing sources familiar with the matter.

The decision not to press charges against Corey Lewandowski is scheduled to be announced on Thursday afternoon by Palm Beach County State Attorney David Aronberg, according to the website.

Fields may still pursue a defamation case against Lewandowski, a source said.

Fields filed a police report last month after Lewandowski grabbed her by the arm and moved her out of Trump’s way following a press conference at Trump National Gold Club in Jupiter, and said he left bruises on her arm.

Police later charged Lewandowski with simple battery, releasing video from surveillance cameras that shows Lewandowski reaching for and grabbing Fields.

Fields would not comment on the record, and Lewandowski could not immediately be reached for comment.

Many lawyers said they just didn’t think jurors would think of this case as a battery, even though it met the technical threshold for the crime under Florida law, which essentially defines battery as unwanted touching.

While Trump initially came out in defense of Lewandowski and claimed the video footage proves nothing, behind the scenes, Lewandowski’s role in the campaign is shrinking, according to Politico.

This is due to concerns among some members of Trump’s inner circle about Lewandowski’s lack of national experience, his perceived unwillingness to challenge Trump and his brash temperament, the website site.
