Police officers in Milwaukee shot and killed a man about a mile from the Republican national convention on Tuesday, authorities and witnesses of the shooting said.

Security arrangements for the convention have come under the microscope since Saturday, when Donald Trump, the former president and Republican nominee for president in November's election, was the subject of an assassination attempt at a rally in Pennsylvania.
