WASHINGTON (REUTERS) - Republican presidential candidate Donald Trump's campaign manager, who was charged in Florida last month with battery on a reporter, will not be prosecuted, Politico reported on Wednesday (April 14), citing sources with knowledge of the situation.

Corey Lewandowski was charged with intentionally grabbing and bruising the arm of Ms Michelle Fields, then a reporter for the conservative news outlet Breitbart, when she tried to question Mr Trump at a campaign event on March 8.

Palm Beach County State Attorney David Aronberg is scheduled to announce the decision not to press charges against Lewandowski on Thursday afternoon, Politico said.
