U.S. Republican presidential candidate Donald Trump, set to visit Milwaukee days after the city was hit by unrest over the fatal police shooting of a black man, said on Tuesday that initial evidence pointed to the shooting being justified.

Trump, who has been vocal in support of law enforcement during a spate of protests around the country over high-profile police shootings, told Fox News that he plans to address the unrest during a town hall meeting on Tuesday in the Wisconsin city.

"It's law and order. We have to obey the laws or we don't have a country," said Trump. "We have a case where good people are out there trying to get people to sort of calm down and they're not calming down and we have our police who are doing a phenomenal job."
