Milwaukee County Sheriff David Clarke was on “The Kelly File” tonight to weigh in on race relations and President Barack Obama.

A Fox News poll found that 62 percent of respondents say race relations have worsened since Obama became president.

“He built this racial divide. It was a wound that had been healing for a number of years, a number of decades […] and he reopened it with his divisive politics,” Clarke said.

Clarke said Obama has benefited from a “divide and conquer strategy,” but that it has been “destructive for America.”

“Who would have thought that after the election of the first black president in the history of the United States that we would need a period of reconstruction to try to put this country back together,” Clarke said.
