Republican presidential nominee Donald Trump's campaign has confirmed he will host an immigration speech in downtown Phoenix on Wednesday night.

Phoenix police have arrested four people for blocking parts of a major downtown road at a protest outside the U.S. Immigration and Customs Enforcement building in Phoenix.
