Violence broke out hours after the shooting, with demonstrators burning six businesses, hurling rocks at police and firing gunshots.
Johnson said the shooting sparked anger among inner city residents who have grown tired of living in poverty for decades.
The solution lies in faith-based community programs that connect people with jobs one person at a time, he said, pointing to Project Joseph, a program his aides helped develop that transports Milwaukee residents to jobs in Sheboygan County.
Johnson's appearance came two days after Republican presidential nominee Donald Trump accused Democrats of exacerbating crime and failing blacks during a visit to West Bend, a predominantly Republican city west of Milwaukee.
Johnson said Thursday that Feingold has accomplished nothing during his tenure in Washington and blasted him for not being aware of rampant prescription drug abuse at the Tomah VA Medical Center.
