Man in blackface punched (TMZ)

A white man wearing blackface got slugged by a protester as police led him away from a demonstration outside the Republican National Convention.

Competing protests set up outside the White House grounds, where President Donald Trump accepted the GOP nomination Thursday night, and activists singled out a man in blackface and told him to leave, reported TMZ.

Police led the man away from protesters calling him out as a racist, but one demonstrator came up and sucker-punched him from behind.

Officers chased the assailant and caught him after a short pursuit, but it's not clear whether he was arrested.
