Trump earlier this year said he could "shoot somebody" and not lose voters

Pensacola, Florida (CNN) Donald Trump said Friday that Hillary Clinton could "shoot somebody" in public and avoid prosecution -- echoing a phrase he once used to describe his electoral invulnerability.

The Republican nominee's comments here came as he slammed Clinton's handling of classified information during her time as secretary of state and lamented federal authorities' decision not to charge Clinton after concluding a lengthy investigation.
