Protester Bloodied As Tensions Flare At Donald Trump Rally In St. Louis

The divisive nature of Donald Trump's campaign was on full display Friday, as the real estate mogul and GOP presidential candidate was greeted by crowds of supporters and protesters at a rally in St. Louis.

The event's tone was set long before Trump even made his appearance. Protesters gathered in the morning outside the Peabody Opera House, where they confronted throngs of Trump fans who had lined up to attend the speech. The two sides shouted obscenities at one another, and on a few occasions, the encounters appeared on the verge of breaking out into physical violence.
