Trump campaign manager won't face battery charges

WEST PALM BEACH, Fla. -- Donald Trump's campaign manager will not be prosecuted on a misdemeanor battery charge after prosecutors determined there wasn't enough evidence to convict him of forcibly grabbing a female reporter.

Police charged Corey Lewandowski last month after determining a video recording showed the New York City resident grabbing reporter Michelle Fields by the arm as she tried to ask the Republican presidential front-runner a question while he was leaving a campaign event March 8.

State Attorney Dave Aronberg said during a news conference Thursday police were right to charge Lewandowski, but the burden on prosecutors to prove the case was higher.

"Although there was probable cause to make an arrest, the evidence cannot prove all legally required elements of the crime alleged and is insufficient to support a criminal prosecution," Aronberg said.

Fields, who worked for the conservative Breitbart News website at the time, tweeted a photograph of her bruised forearm and said she had been yanked backward.

Lewandowski denied grabbing Fields, and Trump stood by him, rejecting calls by his opponents to fire him. Instead, he went after Fields, accusing her of exaggerating and changing her story.
